Hi All

Hoping someone can help.  We have just bought a 40" Samsung Smart TV 5500.  We access My Freeview through our Satellite Dish from the TV.  Often when I want to catch up on one of the On Demand apps I press the green button and get a message in the middle of the screen "Not Available".  Sometimes it will let me in but more often than not I get this message.  Am I missing something - surely it shouldn't be this bad?  Our Wifi is right next to the tv and we have no issues watching Netflix at the times that the On Demand apps are not available. 

Anyone have any ideas?

Thanks.
