I was FINALLY able to download this and check it out a little bit ago . . . WOW. My hat is off to you dude. I've been a fan of Dawn of the Dead for as long as I can remember and this is a project I've wanted to do since at least 1995 when I first learned of the three different cuts of the film!
In fact, somewhere around 1998 or so, I did my own composite cut using the first Anchor Bay VHS release of 140min cut and a VHS dub of the Argento cut (from the Zombie Dawn of the Dead - The Perfect Collection LD set from Japan). I used two VCRs and somehow I managed to sync up the Goblin score into the truck scene footage from the Argento cut . . . though, to this day, I don't remember how I did it. Yes, the quality was iffy at times and the cuts weren't smooth or natural all the time . . . but it worked.
When Anchor Bay finally released the Ultimate Collection, I was inspired to do something like this even more . . . but alas, I just didn't have the time, patience, or tools to do it. So, again, THANK YOU VERY MUCH for this Extended Mall Hours Cut of my favorite movie of all time.
My hat is off to you bro.
