I use Plex for my DVDs that I burned to a hard drive. I don't use any pirated movies or shows. I just burn the hard copies that I pay for.
You can download movies from Netflix and Amazon Prime. Sometimes they expire pretty quick.
Still use an antenna quite a bit too. I just replaced a Winegard Sensar III with a new Sensar IV head. I like checking out local news when I can get it and see what's going on around me. I don't have that great of a data plan so I'm a bit more "off the grid" when I am on the road and I prefer it that way.
This article (toward the bottom) lists all the streaming services that allow downloads.
