you should be able to play off your discs provided you have subchannel reading enabled for whatever CDR plugin you are using. i suggest playing off images though whenever possible, for PAL region games you should make them in a format like .ccd or mdf (see link below).
if you could just post your exact system specs and screenshots of all the error messages you are getting from the logger it would be helpful in answering the rest of your questions.
