The Region setting maybe incorrect.
the Region code on your DVD player, open Control Panel - System - Hardware -
Device manager, and click on DVD/CD ROM drives, then right click on the DVD
drive and click Properties then click on DVD Region.
You can enter a new region and it also shows you how many changes have been
NOTE you can make only 4 changes and the player will lock permanently on the
If you want to play DVDs from any region you maybe able to upgrade the firmware
to make it region free BUT if you make a mistake or installed the wrong
firmware the player will be a piece of junk.
The best solution to make the player region free is to install a piece of
software (Passkey for DVD) that allows you to play DVDs from any region and
Passkey for Blueray that allows you to play Bluerays from any region.
several available on the Internet but my favourite is DVD-Region Free
