Good luck and I hope you get the problem sorted out.
I bought a used Power Mac G4 with Final Cut Pro installed. I have a few Quick Time 22G films I would like to compress to MPEG2 format and burn to DVD. The FCP on my Mac has no option to compress to MPEG2 format. What stand alone compression software would work with the old G4 and FCP 5. Anyone have a clue? Thank you. PBG
