Don: That's your problem. Formac Divideon software. I purchased one of their burners and returned it. The software was unreliable and the external case of the Devideon was cheesy, the burner itself was fine. It was a Pioneer. They also charged me a 20% restocking charge which they didn't divulge at purchase time. I would never use any Formac product again. Isn't Formac out-of-business - bankrupt? So it might be a moot point. I ended up with a bare Pioneer 4X drive and installed it into an excellent Firewire Depot minimalist butter box. After using whatever digital weapon of choice - iMovie, FCP Express or FCP. I export to Quicktime Pro in uncompressed DVD format (fix the sync sound if I shot in 12 bit) use the Quicktime Pro MPEG2 encoder and author in Studio Pro. I use Toast to burn the DVD. The reason for the work around is I am using a G4 Ti 667 DVI and iDVD isn't supported. Formac and their software is the problem. My 2 cents. Rod >Dennis - Thank you for your response. I am using the DVD authoring software >that came with my external burner - Formac Divideon. It does the encoding >and multiplexing and then is supposed to burn the disk. Therein lies the >problem. The disk only burns for 34 seconds and then ejects. If using >Toast would solve the problem, I'm glad to buy it. And, you're right. The >encoding takes 7 hours for a 15 minute Quiktime movie!
