I use gomplayer, but smplayer is great as well.

VLC & DVDFab Media Player PRO 2.4.3.2. Cdt

VLC does exactly what i need

I use VLC for my PC and WD Live Media Player for my LED TV to watch movies

MPC-BE for Windows is by far the best I've used.

If I recall, MPC-HC doesn't have thumbnail seeking, which is why I choose BE over HC. Other than that they're both pretty similar.
I used to use VLC, but it had too many issues in the past, so I've long ditched it.

Personnaly, I use JRiver for all my media needs...Very well designed player with tons of features. I really like music and good sound and I think for sound quality it's also one the best if not the best.

To be honest I think it's one of the few sofwares that worth paying for it.

Give it a try everyone !

PotPlayer. All in One

Potlayer. Fully customizable according to your needs.

I'm on OS X, I use mpv for everything. Good on resources, excellent image quality, plays everything, highly customizable, very minimal user interface (which I prefer). mpv is also available on Linux of course and Windows for the curious.

mostly use VLC player
