As a matter of fact, if you do a little search, you'll find out that the author of DVD Shrink was hired by Nero to write Recode!
They do the same, for the most part. I guess that it is a good bet that DVD Shrink is at the end of development, and we'll need to use Recode in the future.
One problem is that DVD Shrink was also from the "hacking" side doing the decryption, this will not be possible with established company like Ahead (Nero), That reason, and because always DVD Decrypter was better ripper, it is used to rip, and other program to continue processing.
See my regular post, you might skip the blanking for now.
For regular movie that DVD Shrink can rip without problems, you can do 2 steps
1) DVD Shrink to open the DVD disc
2) burn the ISO with DVD Decrypter or other program that you like.
