Did you install the region code selector off the holly wood plus driver disc (or the zip file from their site)?
I have Zone selector installed (I have it for macrovision scrubbing, but setup is the same).
Run the program and open it in console mode if it isn't already (there is a yellow Z on blue circle in your systray right click and hit console)
then you have the popup box, you need to go to configuration and set the location of station.exe for DVD station. then you have to pick the DVD drive from the pull down box.
and check off use this drive with DVD station.
Then on the launch tab pick your zone and hit save.
Then you can press the Run the DVD button.
once you have it configured you can send it back to the tray (the . button near minimize) and then just left click on the Z and pick Launch DVD
Zone Selector will not work if you run station.exe directly, you must run DVD station through ZS.
Not sure if that helped any....
Also for region setting software I think the program is called RCC.exe or soemthing like that...it should be on the driver disk 2 you can download from realmagic.com
