Read error (DVD media)

On DVD media read error may be caused by several reasons. It can happen due to hardware failure - scratched disc, failing drive, or both. But it can also happen due to structure protection present on disc. Please verify that the disc is without apparent damage and your drive is working.

If you do believe that the reason for the failure is a structure protection then the easiest workaround is to open the DVD disc in manual mode per instructions at /manualdvd
