Didn't help, but thanks again.

I keep trying to understand what's going on; a good way to learn, I guess. top 
tells me that XFree is responsible for most of the cpu usage. Can anyone with 
a Radeon 7500 tell me how much cpu is used when watching DVDs and post a good 
XFree config?

thanks a lot

well it IS readonly, but I don't know if that matters
