Was this TOP run on your Myth box? If so I believe part of the problem is your memory. 75Meg is not enough and your system is using swap. Not good for video applications. I have a P4 2.4 with 512Meg and a FX5200 using DVI. 1080i content plays fine using XV. CPU utilization is about 90%. _______________________________________________ mythtv-dev mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-dev
