What type of deck are you using? Can you view the TC on the deck? If so, check the dv tape by scrolling one frame at a time around where FCP says there’s a TC break.
On a not too distantly related topic, we shot hours of footage on BetaSP, in a news broadcast studio (an affiliate of one of the big TV companies). We got the tapes back and were trying to capture them but were constantly getting TC breaks…. in what seemed to be a pattern. Turns out, the cameras and the actual recording decks were set differently. One to drop and one to non-drop. So no matter what we had bad TC. On top of that, our producer did a paper edit to TC window dubs of the tapes, so we were screwed if we wanted to just capture while ignoring breaks. We eventually did that, which meant twice as much edit time.
The studio was super accommodating. Before we knew what the problem was they sent us one of the decks they had used, so that we could capture directly from it at no charge, and eventually a deal on billing was made (we had used more of their equipment than we said we would, and our shoot had gone long as well).
Moral of the story is never assume something is going to be done right, even with professionals. No matter what systems are in place, there’s one major flaw in them all, humans.
