hey guys, like everybody else some xvids won't play on my DVp-642
so i've decided to convert my xvids to divx

the problem is, dr.divx won't retain ac3 audio... it always converts it to mp3 audio... so i decided to rip the video with no sound using dr.divx, and then rip the ac3 sound using virtualdub and then combine them using avimux... but then the movie won't play on my dvd player when I did that

any ideas, what the problem might be? or is there an alternate (better) method?

thanks in advance
