Just bought a Hitachi Android TV second hand. Can only get Netflix, YouTube and prime to work. BBC iPlayer/ ITV / All 4 all show an error saying "Warning: The show that you have chosen is not available" when I try to open them via "favourite apps" on the home screen.

I installed ITV hub separately through the Google play store and it gave me a separate error saying "the manufacturer/operating system provider for this device has not secured the necessary rights for this application." Iplayer was already installed according to the Play Store but wouldn't let me update the app.

Can anyone help? Cheers.
