If I select Catch-up or On Demand on the Home screen the right-hand window is blank apart from the highlighting bar. There is no list. I last used Catch-up on Saturday 30th November and found the problem late last night 2nd December.
Aye, I can picture that - so basically, missing menu rather than specific "no catchup".
Is that the only missing menu - there's what, 6/7 options under the home screen - are any others missing the right-hand panel or just "On Demand". From the top and entirely from memory, you have My Shows, CatchUp, On Demand, Settings... how many actually work?
Personally I'd be thinking box reboot then call faults and report it. Clearly a box fault (assuming reboots don't solve) for my money.
It's just Catch-up & On Demand that have the problem. The Catch-up & On Demand titles are in the left-hand list, it's just that when I select them nothing appears in the right-hand list. I'll try a reboot.
