I typically use Microsoft Movies & TV with GOM Player, VLC Media Player, and RealPlayer on standby for the sake of redundancy.

Case in point, all four of the aforementioned media players had problems playing a 2160p film with a DTS HD-MA main track even after I downloaded the requisite codec recommended by GOM.

To that end, I'm just sourcing a 1080p version of said film until I can perform more troubleshooting.

100% Kodi to keep all my artwork and sorted movies into movie sets. second is VLC but something about Kodi that makes the picture look so much better than VLC

I use VLC Player and K-lite Codec Pack. Sometimes Media Player Classic.

i love potplayer.

but i don't get the madvr filter. it doesn't look that different to me than the default.

I use CoreELEC.
