I don't hold out much hope of this being fixed by writing this as I've seen at least one other thread about it, but ever since demand 5 was updated on my box, it has not been able to play any video. I just get the "whoops, the programme you are trying to watch isn't currently available..." message.

I've tried all sorts of resets and updates, including a few factory resets. Should I be taking this back for an exchange?
