I have had the same problem, the issue is that HDV does not have a good TC track. the only solution i have is to just do a capture now. It works to an extent, you will still get broken clips just not as many. I have the same camera and deck and I hate them both. Be careful with playing a mini DV tape, what happens is that when you flip the FCP system to read HDV, FCP tells you it cant read it because a mini DV tape was played, it is almost impossible to get the system to read a HDV tape again. we had to reinstall FCP several times because of this. from now on what we do is dub the HDV to beta or DV, dv play get in that deck which is kinda funny since it’s built to play HDV.
Thanks a lot,
