Once upon a time, NASA TV was the showcase because it was in MPEG1 and 
everything else was low-bandwidth window cams. Then NASA changed the 
satellite they were using, and the folks transcoding the signal into 
multicast lost the ability to see the bird. RIT has a downlink, but they are 
putting it into an admin-scoped group, and they won't even let me get it ;)

University of Alaska TV used to have NASA TV in between other programming, 
but it looks like they're now filling in time with ResearchChannel. You can 
try DVTS to 233.30.94.33/8000 and see what's on.

At one time, OSTN was providing a NASA TV channel that was accessible with a 
little bit of finagling. Their portal didn't work with my Mac, but I was able 
to convince it to give up the .nsc file for the feed, extract the group, and 
join it with VLC. That group no longer seems to work, and the portal is now 
locked down and won't let me connect. If you have OSTN access you might try 
to find it there. . .
