Copy Protection

If you have difficulty accessing the Internet while using a BD-Live disc, press the Settings button and navigate to the network Setup menu. Select “test connection.” If the BDS receiver is able to access the Internet, then the computer server the BD-Live disc is trying to access may be at fault. check the disc jacket for more information or contact the content provider.
