I have been making the jacket images for my DVDs for a long time with success. The only problem I have with my results is that of the 3 jacket images I make (J00___5L, J00___5M J00___5S), how come the picture quality degrades seriously as the size decreases? The small picture looks like a bundle of pixels instead of representing the original image.

I use TMPGenc Express to convert my pictures to the proper format.
