I have a friend who recently installed Wubi and he mentioned that hulu.com videos are choppy (to the point of being unwatchable) whereas youtube is fine for him. I also have the same version of Ubuntu (10.4) (although, I have a regular install, not Wubi) and I never have problems with hulu.com. I asked if he ever installed Flash and he said "No, it played out of the box without needing to do anything".
What can I do to help him? Should I have him run Adobe's Flash installer? I think, (but am not sure) that I did that on my machine, previously. Does hulu.com even use Flash? One point to mention is that he is running on a laptop, and I am running from a desktop.
