I realise that Netflix and Now TV are technically in competition so doubt that there would be an official Now TV app for enabling Netflix to be viewed on the box.

I do however have Plex installed. Is there a Plex channel for this, either official or unofficial?

I did read that a number of people saw adverts in Currys for Now TV boxes listing Netflix as an option, but think this is maybe misleading.

Can it be done and if so, how?
