I'm giving cdrdao a whirl.  I tried this:

rrarabie at potter:~$ cdrdao copy -v 10 --device 0,0,0 --source-device
/dev/hdb --speed 4 --buffers 64 --reload --eject --on-the-fly --fast-toc
--paranoia-mode 0

And I got this:

0,0,0: HP CD-Writer+ 9100       Rev: 1.0c
Reading driver table from file "/usr/share/cdrdao/drivers".
Found 184 valid driver table entries.
Using driver: Generic SCSI-3/MMC - Version 1.2 (options 0x0010)

ERROR: /dev/cdrom: Need a filename that resolves to a SCSI device.
ERROR: Cannot open SCSI device '/dev/cdrom': Cannot open '/dev/cdrom'
ERROR: Please use option '--device bus,id,lun', e.g. --device 0,6,0
ERROR: Cannot setup source device /dev/cdrom.

I think I understand the error.  /dev/cdrom is a symbolic link to 
/dev/hdb.  It works as a CD-ROM, but I've never been able to play 
audio CD's from it.  Apparently, cdrdao and the xmms need to access 
it via it's SCSI device bus,id,lun.  However, I don't know hot to 
get this.  For my writer I use cdrecord --scan-bus, that only reports
my CD-Writer:

rrarabie at potter:~$ cdrecord --scanbus

From dmesg I see this:

rrarabie at potter:~$ dmesg | grep CD
hdb: CD-ROM Drive/F5D, ATAPI CD/DVD-ROM drive
hdc: Hewlett-Packard CD-Writer Plus 9100, ATAPI CD/DVD-ROM drive

  Vendor: HP        Model: CD-Writer+ 9100   Rev: 1.0c
  Type:   CD-ROM                             ANSI SCSI revision: 02

BTW, my CD-ROM is the second (slave) device on my IDE0.  The CD-Writer 
is the only device on my IDE1.  The box is Debian (woody).

Can anyone enlighten me as to what I've not configured properly?  Do I
need to link /dev/cdrom to some other scsi device, as my CD-Writer is?
