Interesting thought. I moved the Hagrid scene where I did as it looked more like Harry was nervous around Hagrid, thinking he was the one who'd opened the Chamber after the vision from Riddle's diary. Didn't Hagrid say "It's the second one killed this term" or something to that effect?
That would explain why he was seen twice with dead chickens. Being to lazy to pick up my copy and scan through it, I could be making that up in my mind though. ;-)

As far as the audio issue, unfortunately the deleted scenes are only presented in 2.0. I've had to assign them to the two channels in the surround mix, leaving the other channels empty. Now that I'm learning how to upmix, I hope I can fix that for GOF.
