What boggles my mind is that NASA TV is blocking the ability to stream to a Chromecast device. I can't fathom what they think they are protecting. I first noticed the problem when I wanted to watch the Rosetta landing and blew it off as an odd technical problem with my Chromecast that I needed to fix. Trying it again this morning, I realized that this must be something NASA TV is actively blocking. I've never seen this specific behavior on any other site.
Hmm.. I didn't watch Rosetta via Chromecast and I slept through this morning's activities, but I didn't have any problem casting a few videos from their site and the current 'live stream' (although it's a Ustream link right now).
I have ran into streaming issues in the past, but I don't think it's a site specific thing as much as it was Chromecasts lack of support for Silverlight. To watch Amazon Prime videos for instance, you need to go to some obscure setting and force Amazon to serve up Flash videos.
Does NASATV normally use Silverlight? That might be the explanation.. Although the last comment on this Reddit post indicates it's potentially something NASA could fix;
Maybe not NASA themselves since it looks like a third party host, but the way it displays the error, it looks like a conscience decision. Most video hosting sources go right through unless it's a .flv, Silverlight, or code to detect Chromecast and block streaming.
