You can watch CNN Live in your Web browser

I'm watching CNN via Xfinity Comcast.

Had to perform a Silverlight upgrade to get it to work.

When I tried to watch live at CNN I got an error.

Here's a tweet I sent out with the error "NOT PROPER AUTHENTICATION":

Xfinity saw the tweet and helped out:

@stevegarfield Try going to xfinitytv.com, scroll down to live TV and click on CNN. You may need to log in w/ your .net account.

When I tried to watch on Xfinity, I got a message telling me to upgrade my Silverlight plug-in. CNN didn't have that message.

Thanks Marc.
