Bit the bullet and did a clean install of 12; everything definitely working as expected now - haven't gone backwards
; it actually fixed and error notification I used to get after startup whereby the PVR-HTS addon would report an invalid response from the TVHeadend server hosted on this same device - this now connects straight away without error![]()
The behaviour of having to reboot if you restart your router or take the Ethernet cable out is still there, you get the Input/output error I reported earlier if you try to refresh or connect - this was there in 10 and 11 so not new
