Slow UI and recordings not playing on my TV

[smischke]

First of all, thanks for this project.

I've installed your app on my TV (LG 55UH950V-ZA, Firmware version 05.70.30, webOS version 3.4.0). When connecting to my tvheadend server using the kodi user with all channels, die UI was really slow (over a minute for opening the menu). TV streaming from tvheadend was smooth though. So I created a user with only one channel (min/max channel option in tvheadend). Now, the UI is still slow but usable. My recordings are listed, but if I want to play a recording, there's only a black screen. User rights should be ok as stated by setup->connect in your app. I guess the SoC of my TV is a bit old/slow. Is there a way to optimize yout app, so that it is still usable on older hardware like mine? Thanks a lot.
