Just got my macbook,.... trying to use it to watch dvd,... but quicktime doesn't work. DL realplayer,.... doesn't work. Flip4mac,... doesn't work. Then I realize there's a DVD player in the application, not the dock,... and it works. So I can't use realplayer to watch DVD? There's a lock after 5 times of changing the region code,.... is there way to bypass that?
