Also please post you fstab and mtab files. It may be helpful in pointing out the problem. Also have you run yum update on the machine?
(fstab and mtab files posted previously)
I ran "yum update". The box is now 100% up to date. The problem did not go away. On CentOS 5, the Teac DV-516D DVD/CD reader can mount a CD, without any problem. However, it sees a DVD as blank. On Windows XP, it works perfectly, with CD and DVD media. I sent an email to Teac Tech Support, asking for the URL where I could download their Diagnostics for the drive and got this reply:
Unfortunately, no diagnostics are available as checking the read

Disappointing and I will probably never purchase Teac components again. The box is dual boot (WinXP & CentOS 5). Years ago, I purchased SystemSuite 4. I installed that and ran their generic diagnostics on the Teac DVD/CD reader and it passed. I am not positive the Teac drive is working perfectly, but I have a high level of confidence in it.
My belief is that somewhere, there is either no support for the Teac DV-516D in CentOS 5, or, that something required to automount a DVD in it is not configured properly. It can mount a CD without any problem.
