Yes! There is a way!
Just a little more complicated... before I get started, make sure that you download DVD Genie from here:

It is guarnatted virus free and will be the latest version, although development has stopped. WinDVD 3 is supported but I would recommend WinDVD Tweake which we mirror here:

I have written a playback guide here:
http://news.inmatrix.com/dvdguide.shtml and here is the relevent exerpt - it works a treat, I will also try and expand upon it...
======================
Windows2000/XP contains extra region protection, you can view your current 2000/XP region code by doing the follwing:
Right click on my computer and go to Properties, Hardware and then do device manager. Then go to DVD/CD-ROM drives and right click on your DVDROM. Go to the DVD Region tab and this will tell you your internal region code.
Normally you will have a region selected with one region change remaining.
Most software DVD players now use this internal region code, except:
PowerDVD, it uses its own 5 changes system, use DVD Genie.
WinDVD 3, this player does use the internal region code by default but you can modify the registry to make it use its own 5 region counter, use DVD Genie, you must modify the following registry value:
[HKEY_LOCAL_MACHINE\Software\InterVideo\WinDVD]
"IOCTLFIRST"=dword:00000001
There is a way of resetting the region counter to two choices left after every reboot, but requires manually modifying the registry:
Load RegEdit and go to [HKEY_LOCAL_MACHINE\Software\Microsoft].
You should see a random looking random letter key (e.g. " d-`%" ").
If you have a region set, inside this key there is one REG_QWORD value, delete the data that it contains, do not delete this key.
Export the key and save it to C:\Windows (or another such folder)
Create a shortcut in your start menu startup folder that says the following:
regedit.exe /s c:\Windows\regfile.reg
Now everytime that you boot Windows2000/WindowsXP you will have two region choices.
========================
Voila, it works nicely - the first DVD you play will set the DVD region, then you have 1 more choice... if you intend on watching differerent regioned DVDs before youreboot, do some tactical ordering
