for some reason when i use ulead moviefactory 2 to turn an avi file to vob whatever i click the vobs come out to big to fit a dvdr ,the film is only 90mins long,i tried using virtual dub and tempenc to make an mpeg then change it to vob via ulead but then i get jerky playback.im using the trial version of ulead-does the trial version prevent you downsizing the vob output.i tried selecting a different quality but nothing works .thanks in adavnce
