Hi guys, when i bought my car it had this head unit in, with gps etc, and im very pleased with it, it plays mp3, standard cd's etc, but it has never played dvd's, i have checked and its region 2 on the case, but everytime i put a dvd in it says unsupported format or words to that meaning, any help on this, i tried making a music video dvd, this works on all the dvd players in my home, my wifes pioneer in her car, but not mine
