Check that /dev/cdrom is a correct link, for instance
$ ls -l /dev/cdrom
lrwxrwxrwx 1 root root 8 Mar 17 00:42 /dev/cdrom -> /dev/hdc

$ dmesg | grep hdc
    ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:pio
hdc: SONY CDU4811, ATAPI CD/DVD-ROM drive
hdc: ATAPI 48X CD-ROM drive, 120kB Cache

So, it sounds like your cd-recorder (/dev/cdrecorder) is working, but not
the combo drive. To verify that the hardware is working you could try
doing something more manual in /etc/fstab like:

/dev/cdrom              /mnt/cdrom              iso9660 noauto,owner,ro 0
0

and then you can manually mount a cdrom:

mount /mnt/cdrom

This might help to determine if you have hardware vs. software issues.

Good luck,
