Sync after demuxing using dvd lab pro

[gamer_8668]

I have a bunch of mpgs that are in sync ...but when i demux them with dvd lab pro, and compile them, the video and audio are out of sync...any suggestions?

What I did was I converted rmvbs with win avi into mpgs. Then I demuxed them with dvd lab pro, into mpv and mpa, then I made menus and authored it. About 1 in 4 of the movies that i authored were out of sync...any suggestions? thanks in advance.

Are you watching the final results on your PC or your DVD player? When I use DVD Lab Pro the final DVd can often be screwey on my PC, but play fine once I burn it.

it doesn't work on both...i think there might be a problem that the original video was encoded with an audio delay...but i don't know the exact number! so how can you determine it without meticulous trial and error?

but what is really weird is that the all the mpg files work fine in sync, until you demultiplex them and compile them onto a dvd...and what's also weird is that the mpg files work on windows media player, real media player and all of those, but not virtualduomod...any suggestions? thanks in advance

From my experience, sync problems arising from DVD Lab Pros demuxing generally point to issues with the quality of the source. As your source material came from WinAVI converter, I would start by finding an alternate way to produce audio output.
