I'm delighted with my boxee-enabled apple tv. It's great. One of the features I like most is that I'm able to watch tv series not available in Greece (I live in Greece).
Like Comedy Central, for example South Park -I don't mind the ads they insert, even though I would like to be able to pause.
But why on earth, is Hulu and CBS blocked outside the US? Correction: I know "why", don't get me into the legal and regional (business) agreements they have. I rephrase: how does this help them?
What happens, is that most users that would watch Lost, Heroes, How I met your mother, etc. on their browser or boxee, get to download the episodes via bittorrent. This means a) they see no ads, and b) it's easy for them to share the files even with people that wouldn't bother to download them, or don't know how to do it.
CBS, Hulu, and others, wake up! Your decisions on online distribution cost you money!
