The SCSI layer in the Linux kernel is servicing all block devices, regardless of physical bus and controller type (IDE/SATA/SAS/USB/FireWire/etc). "SCSI 0:0:0:0" means "SCSI adapter 0, channel 0, device 0, LUN 0".
The fact that the driver identifies all DVD drives as CD-ROM drives is of no consequence, as the actual functionality of the drive is not affected by this. No specific "DVD driver" is required, just the file system drivers (ISO 9660/Joliet/Rock Ridge for CDs and UDF for DVDs).
Have you tried mounting a DVD from the command line? Does anything appear in the logs when you insert a DVD?
Also, DVDs and CDs use different laser wavelengths, and DVD drives are actually equipped with two separate lasers in order to read both types of discs. If one laser is broken, the drive will be unable to read the corresponding disc type.
Nothing appears in dmesg when I insert a DVD. I get this this when I try to mount from command line

A data CD is automounted by OS. This is what I see in logs

Thanks for the explanation. I will install this DVD drive in a computer that has a different distro and a working
DVD drive. This seems to be the easiest diagnostic.
Looking at the distros listed under your handle, i know that vector comes with libdvdcss installed, but im not sure about redhat. Is this problem occuring under redhat or vector or both?
