When playing a 1080p movie in XBMC i get about 20% CPU usage, when playing the same movie in MythTV i get about 2-3%. I have enabled VDPAU. Why is the CPU usage so high with XBMC? I have tried to disable all settings in the Video/Playback to minimize any differences with MythTV but that didn't help. Is there anything else i could do? Don't really understand why there is so big difference?
