Why are certain Netflix shows jittery on certain devices, while other combinations of devices/shows are not?

I have three devices at home (aside from my laptop) that can stream Netflix. For a long time now, if I stream a Netflix program on my Tivo or Roku, there is a chance that the program will be jittery.
By jittery, I do not mean that frames start getting sporadically dropped here and there like you would see with a bandwidth or CPU load problem, but that from the first second of playback to the last, there is maybe one frame missing every 24 (just to give an estimate). Jittery-ness never starts in the middle of a show or stops before the end.
If I find, on one of these devices, that the program is jittery, then I know it will be jittery on both devices. And, no matter how many times I try to restart playback, or what time of day or what month I try it, it will always be the case. On the other hand, if I play the same program with the Wii or my laptop, it will never be jittery.
One difference between Roku/Tivo and my Wii is that the Wii does not stream HD but the other two do. So, I tried setting my Roku to SD and it still had exactly the same jitters. Aside from that my laptop does HD fine. All three devices are hooked up to the same router via ethernet (and my laptop is wifi), so it is not a wifi issue.
Examples of programs that are always jittery:
- Lilyhammer series
- Downton Abbey series
(It is not exclusively TV shows, but I can't recall any specific movie titles at the moment.)
I have been surprised to see little discussion of people with similar problems, as it seemed to me that it had to be a video-encoding issue. But if it were then lots of people should have been complaining about Downton Abbey and Lilyhammer. So I am stumped.
- Tivo HD (not premiere)
- Roku 2 XS
- Wii from 2008
