I bought this disc in 2010, and it played fine on the Panasonic blue-ray recorder. But recently noticed that the disc will not play (or refuse to move on after warning to the film) on the Samsung blue-ray player. Spoke to tech expert and he points out either RAM + or - is missing from the Samsung player. I compared both manuals, and Samsung player does lack a number of things, but could not pin point. So I may buy different version of DVD, but do not want to face the same problem. Can anyone advise?
