does anyone know how to fix a DVD region error
To set DVD region, go to:
Start->Control Panel->Device Manager
Right click your particular DVD drive which will be listed there and choose Properties. In the window that opens click on DVD Region Tab and select the region you want. However be careful as the number of times you can change the region for a drive is limited.
Another option might be to use DVD softwares that crack the region specific issue of the particular DVD that is causing you a problem.
