I just installed OpenSuse, all the codecs and VLC. But I have a problem: On mkv files, only sounds is playing and on avi files the image is shattered and opened in a separate window from the original VLC one.
2 possibilities #1 that mkv file only has sound so there is no video to play if there was it would open in a new window like the avi file #2 you have mixed/missing packages, how and from where did you install vlc? For multimedia to work you need to have the packman repository and you need to do a full vendor switch with it https://en.opensuse.org/SDB:Vendor_change_update#Full_repository_Vendor_change
