I've a 37PFL7666T and whenever I play a program via iPlayer (connected via wifi) it always drops after 20 mins and returns me to the program selection screen. The TV needs to be rebooted before it will play the program again.
I don't have my firmware number to hand.
However, iplayer plays perfectly fine via wifi on my laptop and iPad.
Has anyone else experienced a similar issue. It is an app problem or do I just need a firmware update?
