So Hulu just released a new desktop app a few days ago ( I am a little slow) . From first impression its farily well done for a beta release. To be honest I like it better then the boxee interface. I watched a few shows on it and everything seemed to work well. My main purpose is to open it from MediaPortal. The best thing about it was it worked well with the remote, once you got use to the buttons.
From what I could tell about the app, it was just some kind of flash overlay. Other then that not much to write about it other then it works!!
