Stupid, to ask questions like this is not stupid at all, but when Spikey tells you that there is nothing a player can "change" or "turn off" on a DVD, it is stupid to say that he is wrong. He is not.

Want proof? Play these two DVD's in another player, and then report back here and let us know what you discovered. Also, let us know what make and model this player is. Read the manual.

Why? Most players have a "condition memory" feature that remembers certain player settings whenever the same disc is reinserted into the player. That's what it seems has happened here.
