AC3 before the AVI video problem

[No_OnE]

I'm backing up a DVD onto my hard drive with the original 6-channel AC3 sound. The problem is that the sound is always a little bit in front of the video. Are there any programs that can put a delay on the audio so that it plays when it is supposed to? Thanks in advance!

You can remux with VdubMod or adjust at playback with MPC, mplayer, or many other players that support delay adjustment.

If you had demuxed the AC3 with DGIndex, it calculates the necessary muxing delay automatically.
