I was having the EXACT same issues with my standard PVR-250. If I disabled the XvMC it would jump and stutter, but enabling it messed up the menus. I was running the nvidia version 8178 and downgrading to 7676 solved it all. -- Matthew Daubenspeck http://www.oddprocess.org Gentoo Linux 2.6.14-gentoo-r5 x86_64 AMD Athlon(tm) 64 Processor 2800+ 15:46:23 up 6 days, 1:30, 2 users, load average: 0.14, 0.08, 0.10 _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
