I don't know if this is the right area or not, but here goes:

Some WMV's, AVI's and other vids that I've DL'ed, I can burn to/as a DVD no problem. Others though, my converting program (Nero) says that there is no sound stream (even if there is) so it can't burn it/convert it to a DVD. Does anyone know why this is? It seems that about 40% of the vids I've DL'ed can't be converted to a DVD...but they play fine on WMV'er.

Being a PC layperson, I've no clue as to what is up...

Thanks in advance.

Get this handy tool and drop your videos on it. It will tell you exactly what
format the sound is encoded in. Tell us what it says about the sound tracks,
and try the 1, 2 ,3 test buttons at the bottom to test if your system is
reading them properly.
