Anyone else have problems subscribing to the new White House Flickr feed on AppleTV?

[Cleverboy]

I'm trying to subscribe to the new White House FlickR feed on TV.
Now, I suspected it would be as easy as clicking "Add Contact" in the FlickR module of TV and just adding "whitehouse", but after trying various permutations, I've got bubkis. Any ideas?
