I’m reading this thread in June 2011! I’ve just epxperienced the very same problem while trying to capture HDV from my Sony Z5U cmera into my MacBook pro, FCP 6.1, and predictably it is driving me crazy. No time code breaks and the footage is split up in random clips with no apparent relation to start/stop points nor scene changes and 2-3 second loss of footage at cut points. Even more remarkable the problem does not manifest if I capture the same footage downconverting it to DV. I’ll try your solution tonite.
