TC output from FCP

I just got a JVC BR-DV3000U DV deck to use with my Final Cut Pro system. One
of the first things I had to use it for was copying some timelines with Time
Code to DV tapes (the JVC deck allows TC to be set via the incoming signal
on the Firewire). It worked fine - BUT the TC is off (behind) on the dubbed
tapes by 31 frames????? I tried dubbing direct from a camera via a 4 pin to
4 pin firewire cable and it worked fine (identical TCs).
Anyone else experienced this?
