Seems you info was just cut and pasted from inmatrix.com anyway
Whooo the red button to click apply was my idea - thats my claim to fame, I also work over on Inmatrix...
DVD Genie will work with PowerDVD 4, becuase PowerDVD, unlike all the other players, does NOT use the windows code, but uses its own, so DVD Genie will work, there is also a crack to make WinDVD revert to using its code and therefore will continue to work with DVD Genie.
The topic states you want to make WMP region free, this is simply not possible... if you want to play a DVD using WMP it will use filters from one one dvdplayer or another (Cineplayer/WinDVD/PowerDVD etc.) but these are only directshow filters and will always use the internal windows region code, there is nothing DVD Genie or Blight can do about this - its exactly the same situation with Windows2000, the closest you can get is to have the opportunity to change the region TWICE everytime you reboot...Using Information #2 I will attempt to modify it so it is a little clearer... I have also written

also note you must have an RPC-1 drive (region free) before even attempting any of this stuff, or you may hardware block your drive perminantly: (this is also described on the above page)
------------------------------------------------------
How to get 2 region choices upon XP reboot with an RPC-1 Drive:
load REGEDT32 and go to [HKEY_LOCAL_MACHINE\Software\Microsoft]. You should see a strange looking random letter key (for example "`dv:=/") as the first entry, you can see that it has one REG_QWORD entry. What you can do is completely blank out the 'Value Data' field and then reboot your machine.
After the boot, Windows should report your region as unselected and programs requesting the region should see this as "Region 0". The problem with "Region 0" is that it won't work on all titles, especially MGM and the new RCE titles (such as The Patriot).
Once you have blanked out the QWORD value, you can always export these registry entry and have them loaded automatically at boot time by creating a short cut that will run the registry file ("regedit.exe /s filename.reg") within the startup directory. This should be especially useful with the "Region 0" setting.
You will get 2 region choices everyboot and that should be enough, I have, like I said, got a complete guide over on

Outlining most DVD region info, down the bottom is Win2k/XP section...
Now if you managed to read all that, gimme some feedback
