HOW-TO:Modify the video cache - Official Kodi Wiki
That's the way how the video cache is being modified. Please post your advancedsettings.xml
Maybe there's something wrong inside it.
Isn't the pvr chaching disabled as the pvr protocol is for LAN only ?
Kodi PVR isn't build for wireless/internet connections.
see here -> HTPS low trought put · Issue #286 · kodi-pvr/pvr.hts · GitHub
No real workaround avaible that I am aware off. I am using pvr over wlan too, but my signal is good enough - best workaround that comes to my mind is to transcode the stream.
And this cache work over LAN with PVR on older Kodi version...
This function was removed for whatever reasons, so maybe you should open an issue at your pvr.abc issue tracker or go back an kodi version and never update again (as it is unlikely this is changed in future without someone reporting issues). Maybe there is an other workaround I am not aware of.
