We have the same problem with audio problems during capture. It seems to drop a frame of audio every so often. No pattern to the problem, and if we recapture the footage it is fine. If we capture through the Cinewave system it is fine–the problem only occur via firewire. Oh, and this machine is still running FCP HD with Medea hard drives.
I’ve tried everything over the last year to find the problem without any success.
As far as audio sync goes, I’ve only noticed a problem with captures over 30 minutes.
Anyone else with similar experiences
