I was able to run the app on my Sony Bravia W7 through the Hotel/Pro Mode procedure, and uploaded a very short playlist (that works fine on my other LG TV).
The problem is that the app does not play any of the channels, the screen is black, it just shows the title of the channel at the bottom with buffering simbol that after few seconds turns into the red error simbol.
Any help would be very appreciated!
Thanks
