Hi! Brand new Catalyst Pro system with a Mac Pro. Using mostly one layer. Going to a projector 1024 x 768. What codec should I use?

Too lazy to do all the tests...

And another question; if I render to DV, playing the movie in QTP will render it in low quality. Do I need to "cmd + J" and click in the high quality button, or does the Catalyst do this for me?

Thanks!
