Assuming you have good OpenGL (and, any good mythfrontend system 
should), then, that's my understanding.

Note, though, that OpenGL (and, TTBOMK, VDPAU) isn't guaranteed to 
actually reduce CPU usage--as described in the posts I linked, and as 
mentioned by Andre in this thread.

And, as Andre also mentioned, the marketing types really seem to like 
the complex UIs full of graphic elements--the kinds of things that, 
TTBOMK, you can't do once you enable the hardware-accelerated video 
playback.  So, it's quite possible that sites may not enable the 
acceleration--after all, Windows users don't generally see problems.

Also, I am not a Flash guy--so I may be way off.
