You're wasting your time. The new BluRays are of lower visual quality than the old DVDs since FUNimation thought it best to use destructive filtering (excessive degraining and sharpening) to make sure as much of the image gets ruined as possible. Also, up to 40% of the image material was cropped off to get it into 16:9 format, which is not exactly helping either. :P
Can you reupload these link in katfile?
