Ok, now I get it.

The problem is thatthe cpu usage when using the software scaler with -vo xv is the sameas with -vo x11, so I might as well use x11 and leave xv for HD (thefonts look good with xv when the content is HD). Anyway, thanks for the explanation. I'll wait until the open sourceradeon driver supports -vo gl at a decent speed in r6xx video cards,then.
