I'm also curious as to how the mono of Jaws is on the Blu-Ray. I have the 2012 DVD and after watching it with the mono I think the mono mix on the 2005 DVD is somewhat better. I noticed a little more clarity on the older release. One thing I noticed is that the sound of the shark crushing up the cage around 1:56:07 sounds a bit drowned out on the mono mix on the 2012 DVD than the 2005 DVD. I also was checking out the 2012 DVD for E.T. and the music sounds odd during the close up shot of the agents rifle. It sounds like it almost switches to a mono mix and cuts back to regular when it cuts to Elliott closing his eyes. Anyone got anything on this???
