I've just received my TV and I'm experiencing a couple of problems.

It came with the latest firmware version. Netflix, iPlayer and Demand 5 work fine.

The issue is when I try and use some other apps. Most of them, including the Plex app, come up with a black screen, and small words in the top left hand corner saying 'Not Found'.

If I try and run the Opera TV Store, a message comes up saying 'We are sorry but your device is not supported.'

I've tried searching the internet for other people with the same issues, but not found anything. I've also tried a factory reset on the TV.

Can anybody help please?
