Alan: Today, I removed the Teac DV-516D DVD/CD reader, manufactured October 2004, in Japan, from my daughters box. I temporarily hooked it up in my box. The exact same problem! I could not see the contents of a DVD-R, but, I was able to see the contents of my Knoppix Live CD, without any problem. So, I did not bother with the PITA of removing the DVD/CD reader from my box, and trying that one in my daughters box. I booted my daughters box with my Knoppix Live CD V. 5.1.1 and it also showed the FC6 Install DVD to be blank. I suspect: (a) The Teac DV-516D DVD/CD reader is not supported in this kernel or somewhere else in CentOS 5. or (b) The DVD/CD reader is somewhat faulty. (c) However, Windows XP shows it to be "OK" and I can see the contents of the FC6 install DVD OK, in Windoze. Also, I can boot from the CentOS5 and FC6 Install DVD's, without any problem. And, I was able to mount the FC6 Install DVD, in a terminal and install the RPM I wanted to install, without any problems. Thank you, very much, for your time and ideas! Lanny
