This is a really strange problem that virtually started overnight. Prior to that VLC has played everything flawlessly. But noew when I attempt to play any files with the . mkv extension, nothing happens with regards to video or audiio playback, and my page file usage instantly jumps from a few hundred megabytes to two point something gigabyte!
If I go into Processes and close down 'vlc.exe' I can run other files (.avi, .wmf), But if I don't do this, vlcplayer will not respond to any new palyback requests. I have tried uninstalling vlc, downloading the newest installer. resetting preferences, cleariing my page file.. I'm by no means a superuser, so any help would be much appreciated!!
