What player do you use to watch movies through?

Media Player Classic, it's simple

Plex

VLC on my computer and Plex everywhere else.

I use VLC on my PCs and kodi on other devices

I had troubles with VLC, so I always come back to Media Player Classic with K-Lite - always works :)

I use xtreamer prodigy 4k (plays anything) to stream to my sony 4k tv, connected through wifi netgear x8 from my computers usb 3.0 external hd's.

I use for Kodi for my media center and use Media Player Classic player (the BEST) for my external player.

PotPlayer for me :)

PowerDVD 17

VLC media player on my PC hasn't given my any problems yet.
