Speaking of Hulu Plus, I was able to download the software on PS3 yesterday. I couldn't get to my Hulu account (needs to get approved) but they do have about 18 sample shows/movies to instantly view.
It now has HD settings at I think 2.6 and 3.2Mbps. The HD content looks much better than SD but not quite up to par with Netflix HD at 2.4Mbps. Good enough though. The 1Mbps SD content does not look nearly as good as Hulu Desktop at 1Mbps. Still in beta so hope they improve the SD side.
