I have a .mp4 H.264 file with AAC audio, and the audio/video are a bit out of sync. I'd like to move back the audio about 100 or 200 ms. Is there a way to do this?

If not, the original HD video is still in EyeTV and I could export that into a certain format and sync the audio & video in that state and re-encode to H.264 after doing that.

I've tried syncing before, with ffmpegx and maybe a few other programs, but I've never found a way that works.

So I guess my core question here is... Is there anyone who has successfully changed the audio/video sync of an EyeTV HD program before? And if so, what steps are needed?

It would be a *huge* help to me if someone could show the way of doing this.
