Hi Dan,
interestingly, yesterday (October 3rd) I again had problems with the wrong region code, too. After upgrading my PC with a new motherboard and processor, I decided to reinstall windows with all drivers and programs. The system image was backed up using Windows Backup. Everything (including PDVD 11) worked fine. Unfortunately, I then tried to install a very old (2002) hard disk utility - resulting in a bluescreen. After rebooting, everything worked fine again - except for PowerDVD 11 ! The region settings once again have been set to 'A' with no changes left ! System Restore as well as restoring the system image - without previous formatting of the hard disk - didn't help (!). This means that the information isn't stored in the registry or other system files !! The only alternative would have been formatting my hard drive and - again - do a clean install or try to restore the image.
My last best hope wasn't Babylon 5
, it was the Passkey tool - and yes, the region settings could be set to 'B' with 5 changes left. Once again I did a system restore to a date before the installation of Passkey, and - I couldn't believe it - PDVD 11 still displayed the correct region settings, even in the absence of Passkey !
Unbelieveable, isn't it ?

(The good news, however, is that most actual Blu-Rays are more or less regionfree.)
