Hi Everyone,
Recently I found where PowerDVD stores Blu-ray region information and how to reset it.
Not a big deal compared to what you have done (found keys etc.) but still this can make someone's life a bit easier.
PowerDVD manages this information differently in XP and Vista.
In XP, it is stored in registry here:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\CLSID\{631400EE-60DF-4014-8A01-67106E57BDA8}]
@=dword:00000002
[HKEY_CLASSES_ROOT\CLSID\{9CB23675-4229-4630-AFF6-3668BA6AF33E}]
@=dword:00000004
Under the first location it stores the region (1 - Region A, 2 - Region B, 4 - Region C).
The number of remaining changes is stored under the second location. Every time you change region in PowerDVD, this number is decremented by 1. You can just put there something like FFFF and forget about it.
By default, there are no values in both locations. PowerDVD interprets this as Region A and 5 remaining changes. When you change region for the first time, it puts values there.
In Vista, region information is stored in Alternate Data Stream (ADS) attached to the file "CLDShowX.ini" located in "C:\ProgramData\CyberLink\PowerDVD\". You can view the content of that stream using, for example, "ADSLocator.exe" utility. If you run out of the number of remaining changes, just delete that file. Next time you start PowerDVD, it will be recreated with default settings.
P.S.: BTW, another file in that folder, "001.FCL", also has quite large (23K) ADS attached to it. Maybe some important stuff in it?
