encoding xvids with ac3?

[tomskinator]

When encoding dvds to xvids and keeping the original ac3 audio, will this prevent the loss of audio sync??

[anonymez]

audio sync issues shouldn't arise at all unless dealing with VBR audio. quite likely your ac3 is cbr so nothing to worry about

i see...
ive been using autogk and had some sync probs with it
batman forever was good until about half way thru then the sound went out
2 other movies were out all throught the movie
so if i set the audio to cbr i shouldnt have these probs??

thanks for the help

don't use autgk myself, but iirc it uses besweet for audio. search http://forum.doom9.org/forumdisplay.php?f=28

One theory I have read is that AutoGK sync issues are due to improperly ripped protected DVD's. Of course the cause could be something else and keeping the AC3 may or may not help.
