Does anyone have experience with 1080p video in Linux with the Intel GMA 4500MHD integrated video?

I've heard that it can handle some 1080p video without dropping frames, but once you get up to videos 20gb in size, it starts dropping a lot of frames.

Specifically, could this board output 1080p video to one 1920x1200 screen while in a dual-display configuration with another 1920x1200 screen, without dropping frames?

Any anecdotal or objective evidence you could provide would be very helpful.

Thanks,
