Does Silverlight or Flash support hardware acceleration? Is work being done by the GPU or only the CPU? I believe Netflix View Instant uses Silverlight, does this support hardware acceleration?

Silverlight -- as of Silverlight 3:

Another new and notable feature of Silverlight 3 is support for hardware acceleration. In Silverlight 1 and 2, all rendering was done in software, which meant that the performance of complex animations and video playback depended heavily on the capabilities of the host PC. Silverlight 3, however, can take advantage of hardware GPUs. You can see this for yourself in Beta 1 and even measure the impact that it has on performance and CPU usage.

Flash -- as of Flash Player 9 Update 3:

Another very exciting new feature in Flash Player 9 Update 3 is hardware scaling support for Flash Player—which lends itself perfectly to enhancing the video playback experience of HD video in full screen—especially when you consider the size of HD 1080p video (1920 x 1080). The new hardware acceleration was not built solely for the new H.264 video capabilities. It also helps with larger On2 VP6 video files and the display of SWF content in general.
