MythTV was the reason I bought and assembled my first x86 PC. I even bought a copy of Red Hat Linux 8 Personal (before Fedora) to run on it. That system became my main desktop PC and is still running more than 20 years later -- like a Ship of Theseus, with every hardware and software component upgraded multiple times. I'm not a progammer but I wanted to help fix bugs and add features, so it was also the reason I learned C++ and MySQL.

I still use MythTV (with additional PCs as backends and frontends) to record Comcast digital cable with HDHomerun Cable Card tuners. It also serves my small library of music files and can play DVDs and BluRay discs. I've ripped 4k UHD BluRay discs using MakeMKV and MythTV can play the files but the colors are wrong since a lot of the plumbing needs HDR support.
