hi, i've noticed "lip sync" problems in a few dvd's. hannibal - dts - i notice the problem not too far into the film. snatch - dd5.1 - about half way through the film. i switched to the dvd menu and back to the film for snatch and i went back a chapter for hannibal and after this, i didn't notice the lip sync problems. not really got a question or saying anything important! just wondering if it's common, a disk or player problem? i use a playstation2 with a h/k3000 amp.
