(I tried a search, but didn't really see anything...)
I was trying to watch NASA TV last night on my Droid, and couldn't. Big fail there. Now, am I missing something?
From the NASA TV site you can use a variety of media types - Real Player, Windows Media, & Quicktime.
One site that carries NASA TV (spaceflightnow.com) but I can't use that until we get Flash on the phones.
Am I just out of luck?
