I was asked to ask you this:
Did the 30i dubs have the same TC as the 720pHD original tapes?
Did you try modifiying the 30i SD sequence in a 1080i project?
In a 720p29.97 project, duplicate the SD sequence, put it into it’s own bin, right mouse click on the sequence, Modify, Set Format, select 720p29.97. This should create a new duplicate sequence with a 720p29.97 Format. Decompose the sequence to the desired resolution. Compare the 720p29.97 sequence to the SD sequence. Do the master clip TC match?
