I have a 70 min timeline, when I play more than about 20 min without stopping the following often happens:
The video freezes
The sound keeps playing
The cti goes to when I last pressed play and freezes.
If I hit stop and play again it plays from the origional start point.
The point it stops at can be an AFX link, a caption or just a straight video clip.

The only explanation for that behaviour is some background process that kicks in with some regularity and eats the resources available at that specific moment. It probably corrupts the regular output and changes the playhead, but it will be hard to find the culprit.
