that's a fair point actually, GPU acceleration is only on the version 10.1 beta... but even if it doesn'taccelerate, it still needs needs to throughput and scale the video, which on a big screen with a weakish gpu (4650) adds up to a 30% load. Definitely not power or heat, doesn't get above 40 degrees in my well cooled case, not even enough to get the fan running...

It crashing without acceleration would suggest a software/driver problem, rather than a hardware problem. Thanks!
