I need help with my VLC player

VLC player must support the MKV video format. I don't know whats wrong with you but for me it is working. Make sure that you are using the latest version of VLC player. If you are already using it then make sure the files are opening with VLC player. I mean you can use option 'program open with' and choose VLC player to play the file.

If you are still getting problem then you can go for alternative of VLC player. Classic media player is the best one working for me.
