Channel 4 now have a good amount of their 4oD content on YouTube. That's a really interesting move, because it puts the content on a far more accessible and higher quality platform than their internal 4oD server. Presumably it reduces their costs, and at the same time makes the viewing experience much better for the user. The videos are full of adverts, so I assume Channel 4 still make good money out of it too.
Now the down side – you can't embed the video, so it's not as seamless as it might be to do something like bring it in to TunerFree.
And then the really bad news – Google are clamping down on people enabling access to YouTube on the TV. They have already been aggressively chasing Popcorn Hour for enabling YouTube access on the TV, and reportedly want a 7 figure licensing fee from anyone who wants to do it.
Fortunately TunerFreeMCE has a great plugin system which allows YouTube's public RSS feed to be read, and allows TunerFreeMCE to link off to YouTube to display the video. Since it just uses the public feeds and direct access to the site, it isn't breaking any YouTube rules. Click here for the plugin.
