Strange Error when I insert any blank CD/DVD

[fanatictom]

I have a Macbook pro (2.16GHZ) with a superdrive and it reads and ejects CDs just fine...except when they are blank. When I insert a blank CD or DVD, the window pops up and tells me I inserted a blank CD/DVD and asks me what I want to do. I select Open in Finder and then I get the following error:

"The disc cannot be used because it is not recognized."

This only happens on BLANK media. Any ideas?

Here is my system profile for my DVD burner:

I am having the SAME EXACT problem on my G5 desktop. (PPC). I posted this on MacFix it earlier today:
Whenever I insert any blank media (CDR, CDRW, DVD, etc), the finder says "The Disc Cannot Be Used Because It Is Not Recognized" . However, if Toast (v7) is open, it recognizes and uses it no problem. This happens to both my internal and external CD/DVD combo drives -- the internal is Pioneer and the external is Memorex. It started happening sometime after one of the last two security updates, but I don't know which.

It's odd because I know this is a good batch of CDs, having gone through nearly 80 of them since I bought them.

This person on another board is having this same problem as me (Feb 12th 2007) post so I'm not alone. They have a different drive than I do as well.

Any assistance would be greatly welcome.

Based on my Google searches this doesn't appear to be a common problem. That or we're both idiots and it's something really silly
