Are the above settings indicative to the size of the original source disc. If so at what sizes would you choose the above options. I have tried on several discs, latest being "Chronicles of Riddick" and can see no difference. Are there any filters that can be used with shrink? When I use DVDRB with CCE I can use deen and undot. These really help clean up bad transfers and high compression artifacts. Yes I use other transcoders, but I really like the simplicity of Shrink.
