Blocks on HDV playback in QT

Here is a screenshot of what I am seeing. http://2ndmileproductions.com/downloads/Picture-1.jpg
The glitches happen on a 1080i file exported from FCP when viewing them in QT. BUT when I scrub back frame by frame using the arrow keys, no glitches. They dissappear, meaning they are not "embedded" in the file. If I view the same file in FCP, no glitches at all.
The screenshot is from taking the 1080i file from FCP and exporting from QT at a 720p. Scrubbing back reveals that the glitches are embedded in the file.
From the screen shot you can see that the glitches are overlaying 2-3 frames from the previous cut. It seems to happen 20-40 frames after the cut.
Playing the file back in VLC reveals that about the same time these glitches appear, the video stutters, but does not glitch.
If I down-convert the HDV file to an MPEG through Compressor, no glitches.
I hope this helps as this problem has been bugging me for a while now.
