Ok, this is what I did:

- uninstalled DVDFab decrypter
- Deleted all associated files
- Found .pf file in the windows/prefetch folder and deleted same
- cleaned registry
- downloaded DVDFab Decrypter 3.0.8.0 from CdFreaks
- re-installed
- Tried to decrypt Monster's Inc. and immediatly ran into read errors.
- left the movie in the drive.
- uninstalled 3.0.8.0
- I did not clean the registry or delete any files
- re-installed DVDFab decrypter 3.0.2.5
- decrypted Monsters Inc. with no read errors

The problem remains consistent. My next step is to try the same DVD drive in a different computer and see if it has the same problem. Keep in mind that the drive performs flawlessly other than this issue.

I am guessing there is something in the latest update that doesn't jive with my computer. Hardware or Software I don't know.

Thanks for all the suggestions. If have any updates I will post here.
