Hmm. My Duron 1300 decodes DivX videos with ~10% CPU usage (using dfbmga). MPEG1 videos don't take even that much CPU (I don't have any MPEG2 videos). 50% feels like a very high number for such a CPU. The only thing comes to mind right now is write-combining. Make sure you have it enabled for your framebuffer (cat /proc/mtrr). -- Ville Syrj�l� [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-users" as subject.
