I noticed that you get an error from the edit to tape that says "cannot lock deck servo" when you set your in point in your timeline on a transition, including the first frame of a fade up... which is typical if you are inserting at 1:00:00:00, also, if you are working in 10 bit, I have heard that it doesn't like a null video either (nothing in the sequence) and you should fill all gaps with a 10 bit black PSD file.
