PVR tvheadend 4.2 libreelec 9.2.0 on RPi2 w.USB HDD

    Hi I have backend channels etc confiured and working. Also client on same RPi2. I have a 375GB HDD attached which I want to use for recordings and data for NAS access. I have configued backend to save recordings to: dev/sda1/tv recordings but am not sure if this is correct. I have looked (for hours) to find an instruction on how to do this properly but am just getting frazzled and confused. I also gather that 'picons' (whatever they are) need to be re-routed. Can someone please point me in the right direction or help me with correct address and fields please? I would like to do it without SSH/CLI, I suffer from FUD badly. I am happy configuring backend via another (linux) PC. [Thanks in advance.]
