It’s still streaming regardless if the content comes from Netflix or your Plex server dude.
I don't use anything like Plex. Tried that once.
Liked the organization: having the ability to order the library by year and narrow it to actors/directors and such. A lot of my file names are unnecessarily long ("Shining, The [1980, Stanley Kubrick, Warner Bros. UHD-DV]"), which is still more limiting.
The thumbnails were nice, but most Blu-rays come with 640x360 thumbnails that you can attach to the rip, if you don't wanna make your own.
Being able to play media remotely is cool. I mean, it would be cool if that was something I did.
But I don't know why so many people use it to play back their ripped media in their own homes. It's much more resource-intensive than simply using a standard media player. My PC fans got really loud just from searching through my library one time.
HDR doesn't seem to work. Gave me some message about enabling tone-mapping.
Bitstreaming audio was also overly complicated. The options in the app were lacking. I don't think I ever got it to work quite perfectly. Remember the audio not coming through at all a few times.
The synopsis are nice, but I can't imagine ever having so much media that I don't know what I own. Besides, I love watching movies without any idea what they are about.
The user interface during playback was too much like Netlfix. Have to move the mouse to the bottom and click a few times to change an audio track, whereas any media player allows you to just tap a key or right-click anywhere.
I think for some people Plex is a little bit of an e-peen thing.
But you're right, viewing my media over my LAN with Media Player Classic is technically streaming. I thought you were talking about using a service.
