I think sometimes PPT has trouble if there are two CD/DVD drives on the
system. If I recall correctly, it looks for the one with the drive letter
closest to A. [I don't know if that's considered "higher" or "lower." :-) ]
I've not heard of issues with the combo CD/DVD drives, but it's entirely
possible it doesn't properly recognize it because of that.
I was going to suggest choosing "copy to folder" and then burning the
contents of that folder to CD, but I see you're already there. That's
probably the easiest solution -- in fact, I don't know if we've actually
seen any real resolutions for the "not recognizing the CD drive" issue.
