Everybody, listen to this set in 5.1 surround. You will find not only the music errors in the rear channel (left & right swapped) and the loss of background music and explosions, but also the dialog is messed up. Episode Four has places where the dialog keeps switching from clear to not-so-clear like a high frquency filter is being switched in and out. Mr "THX" really should not only be ashamed, but immediately pull all the copies from retail shelves and refund anyone with a receipt full price until discs can be released that are not screwed up. DON'T BUY IT!!!
