I love the ease and choices of having my shows/movies/etc stored on a hard drive.
I mainly use it for my collection of old B&W shows and movies and quite a few modern TV series ie Firefly, BB Theory, etc.
It is especially easy and far more convenient to just click on a folder and choose an episode or start from the beginning and watch an entire series commercial free.
I recently bought a Zidoo Z9S media player because I didn't like the GUI's or limitations of any of my HT devices handling of either a hdd or usb drive. I now have 2 (9Tb total) WD portable hdd's connected to it as well as 2 usb flash drives. All my shows, movies, music, etc. are in one place with a nice GUI. It wasn't expensive and well worth the cost.
MakeMKV is a great program and I use it often. I don't use it for my premium movies as I don't mind taking the time to pop a disk into the player. MakeMKV paired with my Z9S is a wonderful way to store and watch shows.
