I guess it’s not so much “hosting” as having it on your home NAS with some scripts to backups channels and videos that you like. At least that’s what I do.

Thought I should make a point to mention youtube-dl is dead, yt-dlp is the replacement and it works great. Even has a command line flag to make its options work the same as the options in youtube-dl so it can be a drop in replacement for existing scripts.
