Flash does /all/ scaling and color conversion in software, too.*** And,
because of this, it doesn't just send <video size> pixels to the GPU to
scale to the screen size, it sends <playback size> pixels to the GPU.
My Athlon X2 6000+ (dual-core 3GHz) x86_64 system can not do full-screen
playback of Hulu content. Funny enough, it handles CBS's Flash-based
playback in full-screen without issue. So, Hulu's player is either less
efficient or is doing a lot more (perhaps the bitrate/video size is
greater on Hulu).
***Which is why I would /much/ prefer Adobe's adding support for
Xv--which would work on basically any video card in existence--rather
than supporting only nvidia cards run on systems with the nvidia
