<div>My first suspect would be the nvidia drivers. I know that my 5200 can play back anything I throw at it while I've heard of many problems on list here from people using 6,7, or 8000 series cards which you would think would be better.</div>

<div>As for the first, does the effect disappear if you force the scan type to Progressive on the menu during playback? I found that NBC-HD (for me) sends mixed frames which Myth rightfully respects but in actually are coded wrong resulting in poor playback. If I lock the frame type to progressive (IIRC) then it is fixed.</div>
