josch, thank you. That information is very helpful. By any chance did you happen to remove Escient from your CX777ES and try to play the movies? Again, I'm tryinmg to determine if the CX777ES or Escient is the problem. I have a strong hunch that the CX777ES is the problem. I believe that the player is having problems recognizing Sony's use of it's own ARCCOS. The 3 movies you named all came out in 2006 and I have found a more agressive use of ARCCOS in the studio's latest releases. Again, this is only a theory but I'm thinking that the software Sony used in the DVD changer is modified from the program used in single players.

Again, if it's not too much trouble, could you remove Escient and try the movies with just the player.

TIA,
