Just installed boxee and love it having an XBMC user for several years now. I can see this replacing XBMC on my media PC when the Windows version is stable and open.
I'm having a problem with Hulu however. Every time I access it I receive "Failed to read RSS feed." All other feeds work just fine. I tried the recommendations I saw in another post of deleting my profile folder after performing an update, but had no success. In fact, that removed all Internet feeds such that I had to delete the entire BOXEE App Support directory to get it back. Hulu's one of the big reasons I would like to eventually migrate my media PC to Boxee.
Slick interface though!
