I'm wondering this, because I've just read an article about the BBC bringing new programs to the iPlayer only, which uses Flash. Some Flash videos play better than others, but they all jerk and stutter to some degree and that's not acceptable if I'm going to be watching long TV programs. When I check the videos with Fraps, the framerate is never constant, rising and falling by a large amount constantly, which is the source of this jerkiness and stuttering. As far as I can tell, this is inherent in the Flash platform itself as I've seen it do this on every computer I've ever used, regardless of graphics power, brand etc and where there are clearly no buffering issues due to low internet bandwidth. Even if a Flash video were to play at a constant 25 or 30fps it would still be acceptable, even though it produces judder. At least it's consistent. So, is it possible to make Flash videos play smoothly once and for all?
