Hello around 3 days ago my VLC player stopped playing .mkv files. I dont know what happened, because ive always used VLC to play my .mkv files. Heres a pic of how it looks like, it seems like its going to start, but it never does. Please any help? http://s83.photobucket.com/albums/j288/Fredd_04/?action=view¤t=VLCproblem.png
If it was coincident with the installation of some new software you could try a system restore to that point or just uninstall and re-install VLC.
