Bizzarrrrrro HD Clip behavior – Help

Bizzarrrrrro HD Clip behavior –

Source footage is DVCPRO HD 720P30. Easy setup, sequence settings all match. Some clips - not all – shift by about 2 frames when they render. With these “bad” clips you can see the shift happen most easily by setting their composite mode to “travel matt – luma” – as soon as you click on this setting the red render line comes on and you can see the clip shift by about 2 frames – easiest to spot in a clip with action. It doesn’t have to be the composite mode – anything that causes the red render bar to come on will cause this shift.

I have tried

Using the render manager to delete all renders
Trashing preferences
Reinstalling the blackmagic decklink driver

I then moved this clip to another FCP machine and the behavior was the same.

Unless someone comes up with an idea I will recapture the clips that are acting this way but this is part of a huge job where some clips exhibit this behavior and some don’t, with no difference in their clip properties.

For the record:

OSX 10.4.11
FCP 6.0.3
Quicktime Player 7.4.5
Decklink Driver 6.7.1

The clips were captured HD SDI from a Panasonic 1200A.
Of the 2 systems I tested them on, 1 was a G5, 1 a Mac Pro.

Any ideas out there?
