Check DVDs for region number compatibility
For a DVD disc to be compatible with a player, their respective region numbers must match.
These numbers are assigned by the geographic region where the player and disc are sold.
You can find the region number for your system on the bottom of the media center.
If you have trouble playing a DVD disc, check to see if the region number marked
on the disc label or packaging matches the region number of your system. A DVD
and media center marked for use in Region 1 should display the symbol at right.
