Jaunty not mounting DVD's automatically, not resetting FS labels?

Hi,
I'm on an up-to-date Jaunty 32-bit.

There are two DVD drives in this system (dmesg output below).
The system doesn't seem to respond when plugging in any CD/DVD .

I've checked fstab and it seems allright:
/dev/sr0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
/dev/sr1 /media/cdrom1 udf,iso9660 user,noauto,exec,utf8 0 0

When I manually look up the devices in Locations they take a while to spin up, but they do eventually mount.
However, <something> (I suspect HAL, hence this question) then correctly reads the FS Label and names the volume accordingly, but the automagic never does run.
However, when ejecting the CD/DVD and inserting another (and subsequently clicking on it to get it to mount), the FS label doesn't change anymore until after reboot.
