mandriva 64 bit, firefox, flash 10.0.42.34 (released Dec. 8), 3Mb/s DSL, "Sorry, we are unable to stream this video. Please check your Internet connection and try again."

Seriously Hulu, a little "We feel your pain and we'll fix it as soon as we figure out what the crap we did" would go a long way here.
