Movies / Shows randomly stop playing

[Tolerant 74]

Is anyone else experiencing having movies / shows just stop randomly while playing using a web browswer? I run the server on the same PC that I am watching stuff on (using my second monitor), but instead of loading up WMC w/MB Classic (which is installed) I have just been watching stuff using FireFox directly from the server address on my second monitor. For no apparent reason, playback just stops with a message telling me the movie has stopped.  The Error is shown as a "Video Error" and I have to restart or resume the movie (if available).

 

Any ideas?
