Still no solution to this issue?
I've the same problem since the last builds,
Suddenly, Media center start to fork a gazillion of jrworker.exe processes, and at the same time as much "divxsm.exe" processes are launched too. (some times, using process explorer I can see uip to 4 jrworker running simultaneously)
Whats make me crazy is that when this happens the PC becomes horribly slow and that the focus is constantly stolen from the other applications
I've tried to uncheck the "update thumbnails" option without any success.
