There is a problem when attempting to play a folder of mkv files (Media\Open Folder...). In cases other than a folder containing mkv files, VLC will play the files sequentially as expected, in the case of MKV files only the first file appears to be recognised. If the first file is playing and you right click and select Playlist all files have the name of the first file (if 10 files in the folder, this appears 10 times), clicking on any file in the playlist just plays the first file from the beginning.
The file plays without problem. I can play each file if I select it individually (Media/Open File...).
I am running Windows 8 x64 and I have repeated the problem on a Windows 7 x64 machine.
