It all has to do with that little thing called aspect ratio. You'll notice that on both the TR47 and ISOMIX caps, they are both the same size. To my eye, they both appear to be straight transfers from the original source without any resizing. The reason they look squished is because the size of the pixels of 4:3 video are actually .9 rather than 1, if that makes any sense. On your television, they don't appear squished like that.
Zion why do you say we can't do an LD faces benchmark to compare these transfer along with potential restoration. Wouldn't that be the best way to see what is potentially lost in a transfer and what is added with color correction and clean-up? Its hard using the 2004 set as a mark when that cleanup process involves the 9th biggest supercomputer in the world with 1000's of Mac's daisychained...Lowry's work is pretty spectacular.
I only say that because a raw capture of the LD's looks really crappy to begin with and it will look different depending on who captures it and what software and hardware is used.
