Consider the following scenario:
- You have a computer that is running an x64 version of Windows Vista.
- You use Windows Media Player 11 to play a DVD that is set to a region that differs from the default regional setting of the DVD device.
In this scenario, you expect to be prompted with a dialog box that lets you change the regional setting of the DVD device to match the regional setting of the DVD. However, the dialog box is not displayed, and you receive the following error message:
Windows Media Player cannot play the DVD because the disc prohibits playback in your region of the world. You must obtain a disc that is intended for your geographic region.
Note: If you are running an x86 version of Windows Vista in this scenario, you do not experience this issue.
