Ghostbusters Audio.....Out of sync....

[MasterCotrim]

I used Divx 5.1 Pro to encode Ghostbusters in XMPEG. I extracted the audio to mp3 file, than i mux the video\audio with VirtualDubMod 1.5.4.1.

I played the movie...the sound was in sync at the beginning, however, about 5 minutes into the movie it was noticably out of sync.

Someone can help me to solve this problem....THX....:(

If u have used LAME encoding there is probability of the specified problem.First convert it to wav and again re convert to mp3 @bitrates >=128kbps.If problem persists use besweet and the original DD or DTS file from DVD.
