Yes, you need to disable repo pertaining to your dvd drive. (The 'zypper mr --disable 1' command was just an example of how to do this assuming it was repo #1). It looks like you don't have any other repos configured yet? Post repo list if in doubt.
Ideally, you should have the oss, and non-oss, and updates repos eanbled for your openSUSE version. Packman is also recommended. See additional repos as described here:
Additional YaST Package Repositories - openSUSE
Add them via YaST > Software > Software Repositories
When done, you can do 'zypper lr --details' again and post here for someone to check.
