I was using Raspbian GNU/Lixux 10 (buster) and installed tvheadend (4.2.8-34~g24a2f59e9+rpt1~buster) following the pimylife up instructions from the terminal command line.
I was also using the pi to make the changes to tvheadend (lesson learned). The Pi runs off the 480GB solid state drive and I keep a blank SD card in the Pi to prevent the "mmc1: Controller never released inhibit bit(s) error" that is common with my Argon case.
Goals are to have a PVR/DVR media server.
I like having a desktop environment for when I do coding projects with my Pi pico (next project is a wooden pinball/pachinko machine that keeps score via IR sensors)
I liked the look and feel of Kodi with the limited amount of time I've been using it but haven't tried out any other software yet.
I want something that is compatible with the HAUPPAUGE Tuner.
I haven't experimented with other Linux systems so I like Raspbian for when I need good documentation and support.
I have all of my project files backed up so not afraid of taking the nuclear option and starting over.
