Yes, that would be true of anything you record, but movies played via 
mythvideo would likely be 24fps, if you ever do that. 24fps played into 
a TV running at 60fps makes the motion look sort of hard (not a good 
word for it. I find it difficult to describe but it's fairly obvious).

Interesting. Given that my experience shows that the problem is at least 
possible on the FireTV, and as far as I know always present with the 
Netflix app for programs like the Crown because their app doesn't 
support frame-rate switching, I wonder if the difference in your case is 
related to whether the TV can mitigate the incorrect frame rate, rather 
than related to the source... unless the TVs are the same model.

I can quite believe that built in apps work better.
