I earlier posted that when I played the MPEG2's I made using the template for rendering AVI files to DVD NTSC using the MainConcept MPEG2 Template, that the audio pitch was lower than it should have been. I noticed this when I played the MPEG2's back using my Creative DVD software on my MPEG2s. I just tried playing the exact same MPEG2s I made with the current Windows Player and the audio pitch is perfect...BUT, IN THE WINDOWS PLAYER THE AUDIO IS SEVERAL SECONDS BEFORE THE VIDEO!!!!!!! How can two different multimedia players get different results when playing the same MPEG2???!!!!

Questions about MPEG-2 A/V sync can be found in just about every DVD-related forum.

It seems to boil down to this: Software MPEG-2 decoders are not always 100 accurate, and behave differently than the decoders found in true DVD players.

The only way to truly verify MPEG-2 a/v sync, (or DVD-bound MPEG-2 picture quality) is during playback, from a DVD disk, in an actual DVD player. Emulation doesn't cut it.

If somebody has a different position on this I'd love to hear it-
