As for checking the cpu usage, I can do it on my second monitor. (I'm not at home right now, so I can't check it.)
Also, isn't there some problem with the video acceleration on the GeForce 6800GT AGP? _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
