Major glitch with a 20 film that I can't figure out. Please assist.

I have imported and synched sound to .mov files in the past with no issues. But all films have been under 13 minutes.

20 minute .mov video plays perfectly in quicktime.
Imported to PT10.
Thumbnails show correctly for entire video.
Video plays fine until 13:40 then the image jumps back to the start (repeating the first 6:20).
Audio continues to play correctly in other tracks.

Clarification, the image jumps back to the start not the curser, time, sound.
This occurs during playback, scrubbing and bouncing.

The same result occurred when:
Creating a new session.
Importing a different 20 minute film.
Importing the video into a previous session where I had no issues. Though an interesting thing occurred. Initially the video played fine. But when I moved the video track by a few seconds, the initial problem returned. I slid it back to where it had worked, and the problem remained.

Any assistance would be greatly appreciated.
