Want something that can do my watchlater list etc. I think the WD TV Live can do that, but I dont have one where I can get to it to have a play with.

I would like ustream, justin.tv and others on it, but being able to give it a URL on youtube to play would do 50% of what I want, and playing stuff that I currently play on my now dead old xbox would give another 40% so that is good enough if its cheap enough.
