Let me know how it goes with the new ATI driver, I see the people at rage3d.com are currently struggling to get it working correctly with the pundit-R. The frustrating thing was that with the hacked ATI driver and bob deint, the quality was actually very good. I was so impressed with Myth that I actually used it for a couple of weeks before I got tired of pausing/unpausing every 5 minutes. _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
