With the iMac G5 (iSight) and Front Row, you can use your iMac's remote control and Front Row to play a DVD movie disc in your optical drive. When you do this, the movie is actually played using DVD Player instead of Front Row. You can change DVD Player's region code up to five times.
If you haven't set a region code in DVD Player (usually done the first time you try to play a DVD movie), you will see an error message the first time you try to play a DVD movie via Front Row.
If the first DVD you try to play has more than one region code available, DVD Player will prompt you to choose the region code for your optical drive. This can also happen if you are not logged in as an admin user the first time you play a DVD.
If this occurs while the Front Row interface is active, you will see this alert message:
"An error was encountered while communicating with DVD Player. Press the Play/Pause button to go to the desktop."
When you return to the desktop, you will see the Region Setting dialog in DVD Player. Choose the region setting for your drive.
Note: Administrative users aren't prompted to change the region the very first time a single-region DVD movie disc is inserted. Instead, the region of the optical drive is automatically set to the region of the DVD disc that was inserted.
