can anyone help with DVD burning audio problems?
 

Hi, i've only been using limewire for a week or so & I've managed to burn a few DVD's with no probs.... until now.
I use nero 6, and the video file is .avi Xvid. (This is the same codec and file type as I have previously burned with no problems)
The problem being is that whilst the video plays fine on my computer, when I transcoded and burned to DVD and played it on my home DVD the audio is screwed up and sounds like very garbled electronic noise :bangh:
Does anyone know what has caused this problem & how to rectify it?
Also, apologies if I have posted this to the wrong forum as i've only just joined.
Thanks!

What audio & video encoding settings did you use? ie: average & maximum bit rates.
Did you use PCM or Dolby stereo AC3 audio?

Erm... soz bit new to this.... not sure if you mean on nero or Xvid...I haven't cofigured Xvid as I only downloaded recently and figured as long as it played fine on my PC it would be OK???
If you mean on Nero then I didn't realise there were such settings, or for that matter what they do.
Sorry for being so thick but I guess we all gotta start sumwhere!
Thanks for your reply though, if you get chanve could you elaborate a bit?!!

Also... if its relative, I used nero vision express which transcoded the video file for me.

I haven't tried the new Nero so I don't know what options it has. But with Roxio, I have options for encoding both the audio & video. ie: Nero will re-encode the video during the burning process. I would recommend to always use dolby surround stereo audio, & keep your maximum video bit rate at 8 or below. If too high an overall bitrate (video & audio bit rates combined) then many dvd set-top players will struggle to play them properly.

Are you using Nero 6 or 7?

Check your burner options. Once you added the video file to it, there should be advanced settings hidden away somewhere.

This could be codec related

What player does the video play fine with?

If it's VLC Player then Nero won't be able to use those

Ah... i've just realise that Nero (6) does have these setting hidden away and i was always a bit afraid to tinker with em so I had it on Automatic (default) transcoder quality. The automatic settings are..."fast encoding-1pass" (or I could have chose "High Quality 2-pass VBR)"...
and audio was set to automatic but there are the options of "Dolby digital (AC - 3) 2.0" or "stereo".
Which is most suitable?
In reply to sleepless...The video plays fine on my PC Windows media player.
Thanks guys!

Also, as for bit rate I can't alter these whilst the quality and sample rate is set on automatic. Don't even know what progressive and interlaced (top field first), interlaced (bottom field first) means... is that of importance

Always use Dolby stereo. The files you downld will always be in stereo.

2 pass is much better than 1 pass but takes twice as long.

Ok with Nero 6, it's divx codecs might not be as good as nero 7's, due to the newer version divx codecs, & other added codecs including audio. But I might be wrong.

Leave interlaced at default. Depends whether you're using ntsc or pal, video source also is related (eg: from a cam.)
That's more of a ntsc issue. I use pal where I am.

Sleepless will prolly know "much" more about burning with nero than me. I don't often burn videos I've downlded. I burn full quality vids.

It doesn't say Dolby stereo... only

Dolby digital (AC-3) 2.0

&

Stereo

Also, i'm using PAL, and video source is downloaded from limewire... originally a camera recording.
I can't understand it as all the reviews on bitzi are good for this particular vid and there are a lot of reviews/inputs with no reports of problems.
The video is pristine but the sound is inaudible!
I think I may give up on this one!
Also not sure what you mean by "leave interlaced at default"
Also transcoding quality settings are can be set to custom in which i can alter the bit rate which is in kb/s... i'm pretty sure the auto settings for this vid chose, long play - 3382kb/s.
wow, i'm confusing myself now!

Dolby digital (AC-3) 2.0 is stereo.
The video rate you suggested is 3.38 Mbps ... yes that is low & should have been fine even with PCM audio ... but also depending upon the maximum setting. Unless you were using CBR instead of VBR.

Anyway, sleepless will be the best one to help you on this. I don't have the nero experience. My version was 5 which didn't have ability to burn dvd's.

Ok, thanks for your help.... i'll have to have a tinker with the settings!

I have the same problem all the time with Nero as well....
The only solution I came up with was to convert the file with Super and then place it in Nero Vision, it then goes through the transcoding stage again, but for some reason this was the only way I could get that movie onto DVD and have the audio in sync with the movie...
It's a long process, but the only solution I have found....:rolleyes_2:

Link to Super....

Ok, thanks for that... i'll give it a go after I try altering nero settings first.
Just out of interest, did you have problems with just audio being out of synch, or was your audio just a series of electronic noises?

Also, what did you convert your file to?

Mine was just out of sync, but I still think it is the same problem after doing alot of research over at the afterdawn forums...
I also downloaded FFdshow it's an audio codec that pops up automatically when converting your files...
Maybe you could get that codec first and try Nero again and go from there...

In super I used vob dvd compliant....:rolleyes_2:

The videos that you download with Limewire will almost always say if they are AC3 in the filename. And in most cases that will be 5.1 sound. If it says nothing then it is probably 2 channel. This should not have such a large inpact on your finished DVD as Nero should just convert to 2 channel if you chose that. Not sure how the other way around will work. I will probably just copy the channels on to other channels not giving much effect.

Must admit I usually have it set on automatic as well and 1 pass for a video thats around 1400 MB or two pass for videos that are around 700 MB.

Also I haven't used Nero 6 for a while now. Nero 7 has Nero Express and one program and Nero Vison as another (off course using Nero Express for the burn process)

One thing you might look into is if your setting may say PAL or NTSC format. Nero converts it to same format as source, but you can tell it otherwise.

Also interlaced is the normal way to convert to DVD. Even commersially I believe.

If Windows Media Player plays it fine then Nero should be able to use the same codec as WMP did

If you still have problems getting it to work then I would suggest you try the SUPER converter that WW recommended. Just make it to DVD and the use Nero Vision Express to burn it.

Stoopid DVD player
 

Soz for the messin around... i've just tried the originally burned DVD (with audio problems)on my PS2 and the sound is fine????:bangh: :confused: :confused:
It also works on my kids DVD player..... just not mine???
Does anyone know why this is?

really really sorry for the messin about, i'm figuring I just have a crappy DVD player.
But i will take evrything you have suggested into consideration for future burning problems and will save this pg in my favoutites.
Thanks so much for your time.... and if anyone shud know why my DVD player does this plz enlighten me b4 i chuck it out the window.
Thanks ppl.

Could be because of size. Some won't play DVD's bigger than 4.38 GB

Or it can be the PAL/NTSC issue. Could be that yours plays only AC3 and not normal stereo.

There are really so many different kinds of players nowadays that it's impossible to say for sure

As a side note. Funny enough the cheaper players often play more formats. How wrong is that ;)

Almost forgot. Some play only DVD-R and not +R or not RW or the other way around

Do you have a button at the back of your player for the PAL and NTSC, if you do make sure you have it on PAL as that's what you chose in the conversion...If you dont your player may only be able to play NTSC....:rolleyes_2:

Well, i know that the size was below 4GB, and I set it for PAL (as i'm in UK).... so must be the audio options you mentioned, I guess i need a new one... its seems the cheaper they are these days the better, mine cost too much & its crap!
Thanks for your help... I guess i'll have to make sure i set it to AC3 from now on.

If you decide to buy a new one you should go for one that plays DivX and Mpeg 4 as a whole.

Also make sure it plays all DVD formats -R +R -RW etc.

they are often very cheap as well. My sister got one for like £80 here

nope no button at the back so it should be in PAL which is the standard here!
Thanks tho!

Ok... i'll write it down and have a look around for a decent player when I get sum dosh! That shud sort my probs out, hopefully.
Big thanks 2 you all!

Check in the players menu, you may have the choice there...
Im in Oz and ours is PAL also but my old player would play both and the player I have now gives me the choice of either via the button at the back...

Ok... i'll have a look for the manual it came with and experiment with it (as i don't know what half the buttons do on my remote, there's loads!)... but thats a good suggestion as my remote seems to have mode n audio buttons, plus others that i've never used!
Thanks.

Different players have the options in different places. Mine has it on the remote control to switch between pal/ntsc/rgb. Mine only cost $100 AUD & plays everything including mpeg4.

I didn't know we could download multi-channel ac3 dvd's. Learn something new everyday. :D I was just curious how they get the separate tracks (audio files) into the video file ... I guess muxing similar to dvd.

You're correct as always

You have to rip the audio seperate and then mux them together. Hard to get right, but those guys have a lot of training ;)

all i cud find by messing about with my DVD player is that the audio is Dolby Digital 2CH.
Don't really understand much about that... suprise suprise!
Also, it didn't state in in the download title that it was AC3.
At least it works on The PS2, that'll do!
Whats muxing?!!

I dont have 2CH to choose from in NERO, but it does say... Dolby digital (AC3) 2.0
does the 2.0 mean 2CH?

You should just try one of each

2.0 is two channel. Try AC3 2.0 first as your player should be able to play that. Almost all new DVDs are using AC3 sound and then you can choose between 5.1 or 2.0 (7.1 is slowly starting)

Muxing is multiplexing. has to do with interlacing. The same thing actually I guess.

If you don't have a video interlazed then there will be a seperate audio track and no sound on the video file

I see.
I think the original burn I did was in regular stereo (but not sure as I didn't save the project) so i'll try AC3 2.0 and see if that makes a difference.
That'll prob take me a couple of hours to do tho, but i'll give it go as soon as I get chance.
Thanx... how do you know all this stuff, wish I was up on all this!

I often back up my own videos. Found out that DVDs are definitely not indestructible ;)

Ah yes... you can never have too many back ups... spesh when there's kiddies around.
I'll give it a go then!
Cheers All!

If i'm successful I shall post it on... if not, my DVD player shall be leaving thru the window!

Or just give it to someone that doesn't need these options ;)

Would be a nice gesture

Hey ppl... well I tried what you said and changed the transcoding settings to Dolby AC3 2.0 and the higher quality two pass encoding. After a loooong 3hr wait, its still the same weird audio... sounds like the exorcist plugged into the electric supply.... hmmm, but I did make another discovery....
As my stereo is rigged up to the TV & DVD etc, I turned it on and lo & behold the sound is crystal clear... so maybe its the TV?????????
But how can it be the TV when Its plays fine on the PS2 which is directly connected???
I'm figuring it has something to do with the way my TV is connected, yet I don't have this prob with any other DVD's as yet.
My DVD player, stereo, cable box, and TV are all linked up in sum spaggetti junction kinda way, and i'm not fartin about with all those wires when i can just listen to it on my stereo... but was wondering if sum1 cud give me a clue as too why this is??? I'm totally baffled, although its not of great importance... its just kinda buggin me now!
Thanks anyway for all your help :o)
I guess Sleepless wont be getting a generously donated DVD player now tho! lol.

LOL did not mean me. I already have a monster DVD player/recorder which plays just about anything and connects to my PC so I don't even have to burn DVD's ;)

I was more thinking of some friend of yours, maybe someone less well off, or someone that just never gets around to buying one.

Glad to hear you are getting it sorted though :)

HE HE.... lol, well I kinda figured you'd have sum kind of sh*t hot system anyway!!!
I guess i'll make sure I'm stood outside ur window ready to catch in case you shud launch it out in a fit of frustration.... but I doubt it. lol
Of course I wudn't chuck mine, i'm not that tight... I'd use it as a frisbee catcher!
Thanks anyway... just thought i'd let u know.
...lemme know when u wanna donate yours, he he.

hehe. My sister will be getting mine when I decide it's time for a change, and then probably my mom will get hers. I don't donate too far ;)

lol... was only joking... I'd never be able to figure yours out anyway!
I'm gonna stick wiv mine for now anyway, so no shopping trips planned as yet!
Thanks for your time, have fun!
