(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:

the drive needs to be repaired or replaced.

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.
