Just wanted to give a heads up to a new startup called Zevida. These guys stream just-released DVDs directly from DVD players, thereby avoiding licencing conflicts. I just tried out movie with them, and the service is easy to use and streaming is good quality.
I passed on an email them encouraging them to look into support for PBO. They already support Google TV, and of course laptops and handhelds.
Might be a good fit for PBO - if we can get YouTube working, this is likely to work as well!
(I hope this doesn't sound too much like an advert - I really am impressed with the service.)
