I have been told by a person who fixes DVD players that certain players cause problems with certain DVD's. Apparently a lot of DVD players will not read the James Bond collection DVD's. I have them all and eveyone works on mine. However the Toy Story box set bonus disc refuses to load up a menu, yet all scenes are still accesible.

I was told they could adjust the laser, but that may cause problems with other DVD's. They said that no player will play ALL DVD 100%. Seems strange to me.
