Hulu somewhat "working" with "Shockwave Flash 10.1 r2" and "LNX 10,1,2,0". The videos are still encoded at too high a rate for the tablets to handle, but the site seems to accept the Flash version as good.

EDIT: Facebook can't find the camera to record video, but no error messages. I'm trying to find a video there to play.

EDIT: Hulu spends a good bit of time "Loading video...", but eventually gives up with, "Sorry, we are unable to stream this video. Please check your Internet connection and try again."
