Sound lags picture

This can some times be caused by VBR audio encoded files as opposed to CBR audio some standalone DVD players will exhibit sound lag in this case. It is a good idea to re-encode the VBR to CBR audio this usually solved the problem.

Although this is usually with DivX (AVI) files that have been re-authored to DVD-Video I suggest that you convert all audio to CBR to avoid any such errors.

this conversion process it a bit of a long way around I know, but it does work!

1) Open video in VirtualDubMod or VirtualDubMP3 (if there is an index error this can sometimes fix it for you.

2) Ignore the error warning that the video contains vbr audio.
3) Extract audio as mp3 ("demux" in VdubMod or "save as wav", then rename to mp3 in VdubMP3).

4) Convert audio to wav with CDex

5) Open original video in VirtualDub, choose "direct stream copy" for video and "Wav audio" with "Full audio processing" with cbr mp3 compression (and interleaving with appropriate delay if out of sync) for audio.

You could also use several other methods including AVIDemux which uses VDub Mod or scan in the DVD-Video using TMPEnc v4.0 Xpress and applying a time lead OR lag however this doex not solve a progressive lag but can be used to reauthor a fixed error.
