I think I have seen this sort of question before. I have installed 3 Mint distros. My dvd drive worked in all. All video formats play. I really don't remember, but maybe there is an option during the O.S. install procedure to allow proprietary drivers and codecs to install, which I did. If someone didn't do this during install then they have to do it later? Is this correct?
