I've converted my 007 DAD XVID to a MPEG1 file, using Automatic-VBR, 41000hz and everything is great except whenever the characters are talking, the audio seems to get jittery, it sort of "lags".

The Video/Audio Sync is perfect, but this audio while talking sucks. Its sort of like "hell - pause- o myna -pause- me is james -pause- bon -pause- d". The XVID is in AC3 audio, but I extracted the audio from the AVI file as a seperate track, so that shouldn't be a problem?

Like I said, it only occurs whenever the characters are talking, which is rather odd I thought...

Any ideas?
