I've used DVDShrink 3.2 on many DVDs and Rebuilder/CCE 2.5 Basic for a few DVDs and I just now notice the brightness/color of the resulting compressed video is slightly different than the original. Rebuilder/CCE produces slightly darker with more natural looking color -- like using the "Levels adjustment" feature in Photoshop. DVDShrink produces sometimes slightly lighter and sometimes slightly darker results. I did this comparison by opening the VOB files in Media Player Classic and looking at them side by side. Has anyone noticed this difference and is there an explanation?
