Here are my results:
model name : Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz uname -r : 2.6.20-1-686 mobo : ASUS P5LD2-VM 2.0 GREEN 945G 775 average benchmark realtime: 79.5 seconds framedrop: 388 frames dropped, and mplayer did complain once that my system is too slow -- however, this was not noticible on the display, and the framedrop did not start until 3/4 of the way through the clip and came in spurts, particularly when the camera pans over a reflective body of water -- at this point mplayer goes to 100% cpu usage as reported by top, however, looking at the individual cores, only one of them is listed at close to 100% video card: intel 945G drivers: i810 Xorg module version 1.7.2 xorg version: 7.1.1 just for comparison I ran the benchmark on my older system: model name : AMD Athlon(tm) XP 1600+ time: 196.4 seconds I plan to upgrade Xorg soon, and will post updated numbers after I do that.
