I see now that Viking is asking for something different. However I've been grokking CPAN, but I can't find any module that provides that information. You'll probably have to use some other 3rd party utility to grep the information. (such as the cdrecord -V option you mentioned). I'm not at a Linux box, so I can't look very easily at what tools are available there.
Good luck!
