Thank you for all your advices.
Yesterday I tried to playback different codecs and formats.
With a mjpeg I had 60-70% of CPU load; Previously I tested a mpeg-2 and 
the CPU load went to 90%.
In both situation the speed of the video playback was slower than 
normal, even changing the fps of GEM.
I tested the patch on another laptop (core2duo with Debian) and the 
video playback ran smooth with ATI proprietary drivers (fglrx) but it 
ran slow with open drivers, so I think it's only a video driver problem.
