I don't have any other cards to compare to, and my TV-out is so crappy it's hard to figure out whether any picture problems are introduced by the M-179 or the TV-out encoder. I will say that the quality degrades quickly if there's any noise in the incoming signal. As soon as I have some spare time and spare cash I'm going to try out ain Air2PC or pcHDTV card, plus get a TV with digital inputs so I can take the TV encoder chip out of the equation. -JAC _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
