Try using a kernel from the 2.4 series...there are some issues with KT133A
chipset and Athlon optimisations but i've found a nice patch that helps.
Also, you need Xfree >= 4.0 to get the best performance out of your
video card, not sure if it will affect how fast mplayer is though.

What video driver are you using? I'm playing various divx files /w -vo xv
at 800x600, fullscreen....on my 2*celeron at 450 system with allmost no
skips and without -framedrop.

It sure is!

Oh, and try using nvidia's driver, it helps alot.

Xfree 4.1(i think it applies to 4.0.x too) automaticaly detect and
your MTRR registers, you don't need to do a thing (other than enabling MTRR
support in your kernel, of'course)

As i said, try the nvidia driver. If you have xfree 3.x.x try upgrading to
