Thank you Craig for taking the time to be so thorough and helpful. Point taken about skill versus time, and yes, there was a lot of compression going on! My source from iMovie was.dv, I exported full quality into QT, then into FCP, and back again in to QT (no sound). However on my laptop screen, and when projected large (4 foot plus) via a data projector, there seems to be no ill effect. It is only when it goes onto a DVD that I notice degradation (slight on my laptop screen), more obvious via a dvd player to TV, hence my suspicion re the DVD transfer process. I doubt you can add more to what you have already stated – I will contitnue to persevere… no sleep til Wednesday… Sam
