I don't think that there is a bug in the PVR add-on. I can view DVB-T2/Hevc it via Libreelec 7.0.1/Kodi 16.1 on x64, ARM (Odroid C2) and Kodi 16.1/17 on Windows. My backend is the stock Tvheadend 4.1.1945 of Libreelec 7.0.1 on my Intel Atom "server". 4.0.* might be too old for that.

I have a RTL2832 tuner and it works flawlessly. It is the cheapest one from ebay (~16€) - normally noname, sometimes under the name "Astrometa".
