Live tv client specific settings are all screwed up.

Well, that's because I never skinned that dialog. My PVR addon doesn't provide that info (tvheadend) at all.
I can give it a shot to code it blind ?

Yep, I knew that.
You have a RPi now, correct?
In Libreelec addons, install the VDR service, then enable the VDR VNSI pvr addon.
You'll be able to access the client specific settings. That way you'll be able to test it.

I was using VDR for the first time just the other day to test it out, but I wasn't overly happy with it's stability so I moved back to TVHeadend. The only real issue i'm having with TVheadend is that it's instant recording fails on random channels. But that's an unrelated topic.
