is there a way to discover the build of a Leopard installer without actually installing it?

I have 2 burned installers and one has a flaw and of course I forgot to label the builds on either

thanks in advance

If these are standard Apple install DVDs you're talking about, the OS build on the DVD itself should match what it'll install. Check this by looking in System/Library/CoreServices/SystemVersion.plist on the DVD. If it's not a standard install DVD (so you can't count on the builds being the same), use Pacifist to extract /System/Library/CoreServices/SystemVersion.plist from the relevant package -- I think it's generally in System/Installation/Packages/Essentials.pkg, but I don't have a disk to check at the moment.

I don't know if this would work but you could try greping the contents of the cd for the string BUILD?
