Just some questions that might help.
Are you saying that you are playing the videos and after 2 hours and 3 minutes they stop? I believe this is what you are saying, but...
Or trying to access the video beyond 2 hours and 3 minutes is causing a problem? If you were to watch for 5 minutes and then forward past two hours would the problem occur? Immediately or delay?
Have you looked in the error log? Look for the link as to how to turn on debugging. I'm blanking on how to do it working between several apps.
