What is SMPlayer?
SMPlayer intends to be a complete front-end for MPlayer, from basic features like playing videos, DVDs, and VCDs to more advanced features like support for MPlayer filters and more. SMPlayer remembers the settings of all files you play. So you start to watch a movie but you have to leave... dont worry, when you open that movie again it will resume at the same point you left it, and with the same settings: audio track, subtitles, volume...
Plays almost all formats without the need to download and install any codecs yourself due to it being based on
MPlayer. Now SMPlayer supports 
MPV as well.

This is a good video player, just the default theme is very ugly. I changed it to MPC, and now it it very pleasant.
Switched from VLC, Faster. I never found anything better than VLC till i found this. I like changing the skins.
It should be noted that VLC supports skins now, however I do use SMPlayer. It just seems to be that bit quicker and plays digital formats with far fewer artifacts.

best of all
Faster than VLC Player; lately it takes ages to load; sometimes I have been going to task manager to close it and reopen it. I have been searching for an alternative; the best.
sm player is amazing plays videos with no issues! i changed the theme to mpc and is very decent!
My first choice of media player on Linux. A lot more customizable compared to VLC & it was easily able to handle some streams where VLC had failed.
VLC works better when videos are sped up beyond 2.0X though, because the audio remains very clear at those speeds. I have tried up to 3.5X. At such speeds SMPlayer (or mpv / Mplayer, whatever) disappoints. I need such speeds for subsequent revisions when watching lectures.
Best media player. Simple, clear, easy, fast, full of useful functions, completely customizable toolbar and options, beautiful design, a lot of beautiful skins, nice icons, perfect windows integration, it's simply perfect. Is much better than vlc.
