I have had Dish Network for over 14 years and have been wanting something like this for more than half that time.
Roku posted a link on their facebook page today that gives you FREE access to a ton of news international channels for FREE. The PQ isn't great, but it is about as good as Dish Network's feeds of other internationals I have seen. Some of the following are 16×9.
Al Arabiya (Arabic)
Al Jaseera (Arabic)
Al Jazeera (English) – Now also available on the Roku newscaster…
Roku "hidden" FREE international news channels (Al Jazeera/Euronews/Etc)
