I personally prefer Roxio EMC 7.5 [ why don't u download it ]
I then use divx to dvd creator and select the automatic sections.
Roxio then decides whether to use normal or widescreen format or PAL or NTSC format. Depends on what the download was.
The finished DVD is sometimes in PAL and sometimes in NTSC but whatever it is, it always plays on my DVD player with no problems.

Hope this helps.
