DVD functionality all but broken with 2.6.10-1.727_FC3

[Kim Lux]

It is almost impossible to get a DVD to mount.  After trying a
combination of mounting with kdfree, right clicking the cdrecorder icon
and manually mounting, it eventually mounts.  I think it helps to leave
it sit for 10 minutes. 

It is easy to eject the DVD if one right clicks the cdrecorder icon and
does an unmount and then an eject.  This was a problem with previous
kernels: 2.6.9-1.6xx ish.  

I can't burn a DVD at all.  I'm trying to use k3b and getting the
following errors:

The machine is an HP zd7280.  The DVD drive works fine under Windows. 

Let me know what else is needed or if I should enter this in bugzilla.
