Serge, I've been doing some experimentation and i've noticed that when i launch an xvid with : mplayer filename.avi it will play i little slower than when i play through gmplauncher. when i launch it with : mplayer filename.avi > /dev/null (i think thats right command) it plays comparably to when launching with mplayer If statistics make a noticable difference, is there an official command line option to disable them from being sent in the first place? Or would that require modifying each codec?
