two major changes to my system setup

upgrading my mac from 10.7 Lion to 10.8 Mountain Lion

and VLC latest stable 2.0.3

and now all my older files don't correctly display the text from the .ass files, oddly the newer batsu games seem to be subbing fine with the attached .ass files

has anyone else had any problem with the newest VLC update, windows or mac, or could it be mac only problem?
