I've been pretty selective, mostly YouTube channels that do 'Tech Documentary Stuff' cause I enjoy re-watching that. LGR would be a prime example.
However, I integrate all of these in my Kodi infrastructure, so only large channels have metadata online in the TVDB or the like.
For those without, I'd love some tips on something to generate Kodi compatible series metadata directly from YouTube.
Were these recorded with a DVD Recorder? Probably never closed the burn on the discs so they are 'open' and that gets funky with drives that didn't burn the disc in the first place.
