I converted my blu-ray, ISO format. I mounted in Daemon tools lite. For 3D movies, I use Powerd DVD 15. For movies in 2D, I use PowerDVD 15 or Ideer Blu-ray player. My PC is connected to two displays. A 32-inch LCD that I use PC screen, via DisplayPort. And a Samsung 48-inch 3D ( UE48H6200) in the living room via HDMI. All this from my graphics card, Sapphire HD7970 GHz Edition VaporX 6GB.
I am playing all my stuff through my fantastic mede8er 600x3d which is awesome and read every single format
i will soon buy a new one to enable h265
I'm using Media Player Classic with SVP Manager. SVP make your movies play at 60FPS (soap opera effect) which is great! It's a third party software and works even with other players like The Kmplayer or even Windows Media Player.
I just load up Plex on my media server connected directly to the 70". I like to keep things simple.
gom player + Klite Codec Pack
My bluray player and a old Philips 42" lcd.
Vlc Player & K-lite Codec Pack
They are the best
MPC-HC since it will play everything you throw at it
VLC and QQplayer
