Is there anyone who is developing it, or is it completely uninteresting to create one?
I did ask this at Philips Facebook page.
***Q: Plex mediacenter client for Philips Net TV? (Not server, just client) Is it going to happen?
A: We do not have Plex in our development. You can contact Plex regarding this question. We do not build the Apps, we only provide free access to our platform for App developers.***
Philips NetTV apps are built using CE-HTML, I don’t know anything about this standard but maybe it’s possible to port the Plex Web version to the NetTV platform that includes Philips and Sharp devices.
There is a SDK available at Your app on tv. I hope a developer is reading this
