"VLC is the king of media players, It can play all media files, without installing any extra codec packs.The user interface is quite simple but not easy to use, if you are switching from Gom to VLC the interface may seem unpleasant, but it can be changed in preferences, take some time and change the shortcuts and you are good to go.
The extra features of VLC are Online Streaming, it the top player to play streaming videos without web browser.other features like desktop recording and editing are making it more popular each day."They are becoming more and more efficient through each releases of their update.My personal advice, use VLC, GOM and KM player on your computer, update them regular, you can have an awesome multimedia experience.
