I use a Radeon 7500 32MB low profile, which I bought at E-Bay for 18 Euro.
The image quality is excellent, but DivX in MPlayer don't play 100% smooth, altough the CPU usage is only about 30%... any ideas what could be wrong?

I could give my Voodoo 3 3000 a try, just to see if its a gfx card (driver) problem or MPlayer/MorphOS related.
