I actually have the same problem as you. I work off of a PowerBook G4. I upgraded to 10.4.10 and installed Studio One over an old Final Cut (4.5). I tried putting Studio Two on top of it, but still have no ability to capture. Although my camera can be controlled by remote in capture mode, preview does not work, but I get timecode. I also am receiving levels in the audio tab. Were you able to solve your problem? Emptying the cache and receipts didn’t work for me. Please help!
Thanks so much.
