Yes it's true i use it with BeamsTV. You see a blue icon on the channel logo and if you hold down the icon then a submenu appears one of which is CatchupTV. With Beams it is on the main channels and goes back 7 days with a full guide. It's a great feature

I get the blue icon and the ensuing guide but any time I click on an actual show, it just brings up a black screen. the provider works in every other app I've tried though.

Yes that’s true :)
