Re: Your system is too SLOW to play this!
Same video, display set to 1080p60, all videos unscaled/windowed
x11 = fine
xv = video/audio freezes every second or so, X process at 100% cpu usage (X at 7% on laptop)
vdpau = 'System too slow' message, 4% cpu usage.
Definitely something wrong with playback of 60fps video if it can't play a 640x480 60fps video, unscaled with xv/vdpau. Especially considering it works fine on my lower powered laptop with a crappy onboard intel gpu.
