I am having the same problem. The playback worked fine just before i upgraded to the new FCP. Now Every time i View playback on the Cinema desktop monitor the video skips. When i look at my activity monitor there is a large random peak in disk activity that i cant explain ( it seems to correspond with the glitch but i cant tell). also some compressor controllers are not responding but compressor seems to work fine. Are these related or what? Is there something set wrong in my settings or is it a glitch in the new upgrade? I tried all the solutions in the thread so fair nothing worked. Thanks
