Probably been asked before but, when I convert files ( tried four now) using mainconcept mpeg encoder version 1.4.1 the sound is great for about 20/25 mins, then I lose all synch. When I use tmpgenc I dont seem to get any sound at all after 2 or 3 files converted. Checked out the avi's and the sound is good all the way through!!! I want these films to put on to dvd but....... no good without sound. I have read a few posts on changing the sound files for tmpgenc but this seems a bit complicated. The films I am having trouble with are kill bill, predator 2, matrix revs and jeepers creepers 2. Any body got any ideas please?
