Thanks Mike, I'll give that a try tonight. The main reason I want to reduce CPU usage at this point is that I'm playing back 720p HD using libmpeg2 and the CPU is bouncing between around 80% and 93%+, with the result that I'm getting stutter. I'm looking for anything that I can do to reduce the CPU load. I'm running a 2.8GHz P4, and I know people have talked about doing HD on 2.4 GHz machines, so I'm not sure why it's so high. I'm not running any deinterlace. Can't do XvMC on Sis. Ideas? If I can't figure it out over the weekend I'm sure I'll post again with a more targeted subject line. -Jerry _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
