Mary,

Does the HDTV playback just look slow/not smooth or does the playback 
look corrupted, made up of lots of little squares of random colors? I'm 
not certain by your description of the problem in your original post, 
but it sounds to me more like you are having signal problems. If it's 
not the signal, I've also found sometimes Myth seems to incorrectly 
guess at whether the video is interlaced or progressive (either that or 
the format actually does change like crazy), and can result in a similar 
appearing picture, although a little more rhythmic. Setting the Video 
Scan to either Interlaced or Progressive, as opposed to Automatic, 
usually fixes this for me.
