queation about dvd backup programs

I've just tried dvd shrink, it works great except the quality issue, I found the quality is a little bit worse than the original, I dodnt check any compress options and the iso file size is around 4.xxG, it shouldn't have lost any quality, how's that happened? also, I'd like to know the difference between shrink and DVDdecrypter, does the later work in the same way as dvdshrink?

Instead of me writing out long answers I suggest you check out this site.

Its pretty much the golden standard when it comes to learning to back up dvds/cds.
