I'm just now starting on CS5 and the 64-bit environment, so I know there are probably some "operator error" issues involved in my question.
One of my colleagues sends me .MOV files encoded via his FinalCut machine with the Apple ProRes 422 codec. I've been able to edit them in the past on my CS3/32-bit machine.
On my new CS5/64-bit setup, I'm seeing flat waveforms on ALL of the eight channels of audio (there should be audio on two of them in these specific cases). Even when I playback in the native QT player, there's no audio. It seems to be a codec issue to me, but the video is playing, so there's obviously something about the codec that's working. Any ideas?
