Something else i noticed about the audio. The sound effects for part of the detention cell shoot out swapped channels in the 2004 versions. Now i decided to check the Blu-Ray audio and the same mistakes are there. Just check the section right after the Stormtroopers start knocking on the door when 3P0 is on the comlink right up until Leia blasts the hole in the wall. Now this was a mistake only found in the 2004 version and was correct in all the old mixes. You can hear it best if you can mute all channels apart from front left & right. even though the laser blasts are quite fast to keep a track of which direction they are, just keep an eye out for when Han shoots. You hear two clear blasts coming from the left channels when they should be coming out of the right. In this section all the effects are swapped. Now did they really start this mix again from scratch or did they just go and fix the rear channels and dialogue?
