I have been having this same problem of the picture freezing and the audio continuing to play for months and have not been able to solve it. I am on OS 10.4.9, FCP 5.1, Quick Time 7.2. I have 4 external data drives in a FirmTek SeriTek/2eEN4 and a 320 GB drive in the computer, in addition to the boot drive. The RAM is maxed out at 1.5 GB in my G4 Dual Processor. I have trashed my preferences and even gone so far as to do a clean install of both the OS and FCP. I have been through the preferences over and over, but see nothing wrong… No luck.
It does not matter if I capture to the internal or external dives, the playback problem still occurs every once in a while. Even if I am only playing back a clip that has just been captured in the viewer and there is no timeline to overlap on the screen. I can stop, backup and play over the same spot just fine, so the problem isn’t long frames in the HDV I’m capturing as DV.
Any thoughts?
Thanks,
Bill
