How exactly do I change the speed of the video streams? However, a pause and then restarting won't fix it. Stopping the show and then restarting it won't fix it - it takes a soft reboot. >Does it happen with any greater frequency when you are using two >MVPs simultaneously? don't think so. >>Most commonly it starts at about 20 minutes, but not always. > >It may be interesting to try running the mvpmc bandwidth test for 30 >minutes and see how that compares to a 10 minute run.

So what are good settings?
