9.04 Won't Read DVD's

[wmichaelb]

I recently picked up an HP 8510p laptop, and installed 9.04. Generally, the machine works well, but today I tried to install the Ultimate Edition, and found that the machine won't read DVD's. It reads and boots CD's just fine; that's how I installed Jaunty. When I open the fstab file, I notice at the bottom:

# /etc/fstab: static file system information.
#
# Use 'vol_id --uuid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

I notice a "cdrom0" at the bottom. I also notice that the /cdrom folder is empty.

Sysinfo id's the drive as a Matshita DVD-RAM UJ-861H. Do I need another driver? Where do I find one, and how do I install it?

Thanks in advance for any help you can offer. This is a similar issue to:

so maybe we can score two for one!

I have seen certain drives not read CD-RW or DVD-RW disks yet run fine on the CD-R or DVD-R media just fine so if it is DVD-RW you could try changing....

Thanks for the suggestion, but no, it's just a normal 16X DVD-R that was burned at 4X to be sure. It's actually the Ubuntu "Ultimate Edition", and I read the DVD just fine on another machine. Hence my puzzlement.
