I am working on a project in FCP 6, on a early 2008 Mac Pro (8x 2.8, 2GB, 8800GT). My footage is 180p Apple ProRes 422 (down from 2k Redcode RAW). I have a playback projector setup, just because I can, with playback going via Firewire through a DV camera and composite out to the projector. At first everything worked beautifully, but I soon realized that my audio was also going out to the DV deck. So, I happily selected my MP's line out for audio, and now on my playback monitor it only plays a single frame at a time. I have selected and deselected every single playback setting there is. Help?
