How can be CPU utlization while decoding 1080p h264 less than 100% while not using GPU acceleration (X-Video)? I am totaly sure that atom is not able to decode any "normal" real world 1080p h264 video, neither my Pemtium M dothan 1.5GHz does. Even 720p is very offen too hard to decode. I think there is some error in your suite. I had big problems getting 1080p work on intel 2GHz core duo CPU in apple mini, atom has simply no chance.
