I have exceeded 5 times on my dvd player so it is looked on only registering the same region. I know this has happened before (last 5 months) and i fixed it somehow but now I have totally forgotten what I did.
You could always try a software that makes your drive region free.... AnyDVD DVD Region Free+CSS DVD43 OR.... if I remember correctly an upgrade in firmware will reset your region change counter. But there also may be some hacked firmware available for your drive to be region free. Check your drive manufacturer's site to see if an update is available or for a hacked firmware go here.....(use at your own risk) http://forum.rpc1.org/dl_all.php
