Forgot to mention i'm using Ubuntu 11.10 and the video files are 30 fps with the codec H.264 / AVC
Also, while sending an "auto 1" message to pix_film gives smooth playback, the file plays perhaps 30% slow. This doesn't seem to be a CPU issue as the cpu is running between 20 and 30% while playing the file.
in "auto 1" mode, Gem will increment to the "next" frame in each render tick. "next" means that #125 will follow #124 regardless of the actual fps of the video. since your video is encoded with 30fps and the default tick-time in Gem is 20fps you will play the file at a reduced speed. the simplest solution is to raise Gem's framerate.
as others have pointed out, the "blurring" will most likely come from inter-frame compression where you are trying to access non-keyframes and the used backend (most likely gmerlin, according to your settings) does a bad job at reconstructing the image.
