I wanted a zone free DVD player so I down loaded vlc, It worked ok, then my iMac DVD player nolonger let me change zones, I'm zone 4 and the DVD player is now stuck on zone 1. So I thought thats fine I'll just use vlc, however when I put zone 4 disc in, my imac DVD player takes over and tells me to eject the DVD. so I removed DVD player and all its files from my imac. vlc would not work, so I removed it from my imac and redownloaded it. it still wont play, I get These massages. if I put a zone 4 disc in it says "acces_file:read failed (input/output error)" if I put a zone 1 disc in it says "acces_file:read failed (permission denied)" Please Help.. all I want is to watch my DVDs.
