On all three of my FE's, I have noticed the same issue.  It doesn't make 
it unwatchable, but it's as if the video is trying to 'catch up'.  Just 
a stutter here and there, most noticeable as the image pans (and this is 
on both 16:9 and 4:3 tv's).  Since my mythtv setup is so new, it is 
still on my list of things to investigate.
