In FC3 the device /dev/cdrom seems to not be used in most cases.

I find the device is the actual device (/dev/hdX) , and the mount point
is no longer /mnt/XXX but is instead /media/cdrom or similar.

Mount shows me this:

/dev/hdd on /hdd on /media/cdrom type iso9660 (ro,nosuid,nodev,
user=jeff)
/dev/hdc on /media/cdrecorder type udf (ro,nosuid,nodev,user=jeff)f)

Note that I have 2 drives, a CDROM at /dev/hdd and a DVD-RW at /dev/hdc.
