BUT WAIT, More BUGS found in 5.7.2

We seem to have a problem with frames being repeated on capture (using QuickTime v7.1.3). Something that did not happen with QuickTime v6.2 and Premier Pro 1.5 where present.

I digitized with Deck Control a six second NTSC 10-bit sequence. Exactly at 4:29 I have a one frame sync mark. This is a yellow frame with corresponding 1 KHz tone.

When digitized, the sequence lasts for six seconds and one frame, BUT the sync mark is seen and heard at 5:12 on the Premier Pro 1.5.1 NTSC non drop frame time-code 10-bit timeline.

I just captured something else and you can tell that one or two frames are being introduced ever so often as the sound, which is music, gives this error away immediately.

Now, to tell if the capture offset was correct, exactly at the 01:00:00 point, where my capture begins, I have another one frame sync mark. This means that at the start of capture I have a one frame sync point and at exactly 4:29 I have a second one frame sync mark.

On the Premier timeline, my MOV media begins with the one frame sync mark, yet the second sync mark now ends up at 5:12?
(00:01:05:12)
