You have to download whatever thing it is you want to see, and ot takes aaaaages!
I'm using it on my iPad - or rather i'm not using it at all because I justwant to open the app, find the programme and then click play. I don't want to download anything, I just want to watch something. Now. When I click on it.
Like I do on iPlayer.
It's rubbish and I don't bother with it.
