Blu-ray™ Region Code
Region code setting has to be set BEFORE playback Blu-ray Region code setting has to be set before playback. That said, both the DVD-Region Code and Blu-ray Region Code may only be changed FOUR (4) times [yielding a total of 5 regions the drive can be shifted through (the initial code is set by the OEM]. Some drives conform to a different numbering schema than this and allow setting 5 region codes for both DVD-Region and Blu-ray Region, but nevertheless, you are grievously mistaken that the hardware's firmware does not record this! If you go into Device Manager, access the drive properties, you will see a field to establish a different region, but YOU ARE ALSO CLEARLY-CLEARY-CLEARLY informed that you have a limited number of changes (5). This is a well-known restriction that has been around since the late nineties (Blu-ray excepted). The firmware can take a low-level system call instructing it to change regions, and if the PROM (that means certain regions of a special chip can only be programmed once and if 5 control bits have been written OR an increment counting IC that can only move one direction (1,2,3,4,5) and stop changing decoding when the respective cell has the value of 5, then the drive can absolutely and rightfully deny you!). Maybe your problem resides somewhere else, but please don't guess on an answer forum!
"I very much doubt that the settings are stored in the drive as PowerDVD 7.3 still plays Blu-ray just fine and tells me I have 5 changes left. Unfortunately, I needed to buy version 12 for its 3D playback, else I'd be happy sticking with 7.3..."
Yeah, but software cannot be relied upon to alter hardware -- it almost always does, but I dare you to change the region in v7.3 and then change it back. It won't happen if the device manager, which simply queries the component bus for info that the attached hardware items are willing to give up. And it may be that you're seeing things and misinterpreting them. DO YOU STILL HAVE 5 DVD-Region changes available? DO YOU STILL HAVE 5 Blu-ray Region changes available?
Sorry if the trial instructed your drive to change regions haphazardly, but if that is what happened, then the drive is "bricked--forever set to the 5th Region Code Set for DVD and/or Blu-ray parameters.
BTW: Thanks for replying (you didn't) with a resolution or disposition--how did you fix it? Could you fix it? What happened?
Also, the read-'n-parse routine for v7.3 does not read in the realtime values and instead uses the magic number of 5. v11, 12, and 13 all had flaws where they woul send the instruction to change region, but FAIL to record it to either a .cfg, .ini, .dat, etc file or commit the fact a region had been chosen prior and so asked the question each time. Kill the handle of the .dll, and reassemble the dependency based executable. Boom--you're done! That's why we use write-blockers and remove the jumper that controls the ODD 's ability to change--then it will ignore change of region system calls, thus removing the possibility of malware or ignorant users to make such a simplistic mistake (assuming, you never got it working...reply if you did).
