12.2 Install problem

During a new installation of 12.2 when the system is trying to initialize the software manager YaST2 reports "Unable to create repository from URL … " followed by the name of the DVD drive. Thinking this may be a problem with the download, I downloaded 12.2 again (groan), and tried it again with the same result. The DVD drive is working normally (I have W7in stalled on the hard drive).

Any suggestions?
Cheers

Run the media check from the DVD
