I just tried to convert my 600MB file (mind you it does this on all my long movies) to MPEG-2 in TMPGE and when I go to play it, PowerDVD wont let me skip past a certain point. I can convert smaller files to MPEG-2 but not bigger ones. I think this is what is also screwing up my burning of DVDs. Could anyone help me out and tell me what the deal is with my files?
