I know you can stream the usual shows (modern fam, etc) but do you know if you can get stuff like the news and sportscenter? I like watching the nightly news, MH might die without SC:)
so there's a free ESPN thing on the roku newscaster. looks like these are news clips, podcasts or audio of certain programs. i haven't found a definitive program guide for these channels yet, but i think it's just a matter of time. http://www.rokuguide.com/channels/roku-newscaster
for news, there are both a CNBC and NBC news channels. under roku newscaster is CNN and the other major networks news programs. don't forget that you can still access your over-the-air network channels, so if you're able to rig up a DVR function with a computer, you could record stuff from over an antennae to watch anytime you want.
