I have taken various sorts of video formats including original dvd vobs recreating ifo's with ifo edit
Frame rates 25 fps Pal
If I master one of these films on its own using DVD Author it works fine and the audio sync is spot on (PC and stand alone). It's only when I try to add another title to the new DVD that these problems arise.
I've checked the bit rate and these are well with in spec and Gspot states A/V delay is fine before authoring.. However after authoring I'm geting about 120ms Audio drift..
The problem only seems to be when authoring a title in excess of 1hr
