Catch-up TV apps

[Tramlink]

Dose anyone else find that every-time they up date iPlayer, ITV, 4OD and Demand 5 what was working stops.  I have a NEXUS 7 2013 with all the newest updates.

To my surprise only i-Player works all the rest just do not want to stream videos.

Any one ever got all these catch up apps to work?

I-Player is ok
Demand5 only works on wi-fi, which seems crazy for a phone on 3g
ITV and 4OD are both poor. One of them had a problem with ad blocker, so I ditched them ages ago
BUT
Sky Go works brilliant and I can access all, (bar BBC I-player.)
So I'm alright jack
Its almost like the terrestrial channels don't want you to watch on catch up.
