only HULU and CBS are the ones restricted to the US(you can always try and find ways to circumvent this hotspot shield ,US proxy servers etc) there are plenty of other channels (Comedy Central,My spaceTV,Video podcasts ,On networks etc..) plus they are always adding more content to other geographical locations..
How would you go about using hulu on boxee with a proxy? Sorry if this is a dumb question but I haven't used it yet. Thanks.
