I have an IDE DVD-writer and a SCSI cd-rom on my Debian (2.4.22) system. To use xcdroast, I enabled SCSI emulaton and edited my fstab to look as follows
---------------------------------------------------------------------
# /etc/fstab: Tabelle einzubindender Dateisysteme.
#
# <Dateisystem> <Mountpunkt> <Typ> <Optionen> <dump> <pass>
/dev/hda1 / reiserfs defaults 0 0
/dev/sda1 none swap sw 0 0
proc /proc proc defaults 0 0
/dev/fd0 /floppy auto user,noauto 0 0
# /dev/cdrom /cdrom iso9660 ro,user,noauto 0 0
/dev/hda5 /home reiserfs defaults 0 0
/dev/hda6 /usr reiserfs defaults 0 0
/dev/hda7 /var reiserfs defaults 0 0
/dev/sda2 /xtra reiserfs defaults 0 0
/dev/hda8 /dl reiserfs defaults 0 0
/dev/scd0 /scsi iso9660 ro,user,noauto 0 0
/dev/scd1 /dvd iso9660 ro,user,noauto 0 0
----------------------------------------------------------------------------------

My original DVD line (/dev/cdrom) was commented out and I inserted /dev/scd0 (the scsi cd-rom) and /dev/scd1 (the DVD writer).

Xcdroast is happy, but XMMS (amongst others) is not. I know that I have to change whatever points to /cdrom to point to /dvd, but I have no idea how.

For what it's worth, cdrecord -scanbus gives the following output:

Any help, ideas and pointers will be welcome.

you could redirect the link /dev/cdrom to whichever drive your using for audio cd's
ln -s /dev/scd1 /dev/cdrom

Thanks, I tried it, but it didn't solve the problem.

When I do ls -l /dev/cdro* the output looks like this:
------------------------------------------------------------------------
lrwxrwxrwx 1 root root 4 Feb 7 15:57 /dev/cdrom -> /dvd
lrwxrwxrwx 1 root root 9 Feb 5 20:43 /dev/cdrom0 -> /dev/scd0
lrwxrwxrwx 1 root root 9 Feb 5 20:43 /dev/cdrom1 -> /dev/scd1
------------------------------------------------------------------------

Any further ideas?

You can also change the input for the XMMS cd input plugin
Right click on XMMS Options->Preferences
go to the Audio I/O Plugins tab and click CD Audio Player plugin then click configure

Once you extabilished what name has the device after enabling ide-scsi emulation
make sure you have permissions to access that drive as user.
Try using this device first as root and if working properly look for whatever group owns such device and add yourself as normal user to such group.
On Slackware usually disk group owns cdroms, dvdroms etc.
May be debian has different setup
Hope this helps

Thanks for the advice. I'm at work at the moment, so won't have an opportunity to try it until tonight, but will post the result as soon as I've tried it.

Problem solved.

I checked the permissions and they seemed to be ok. Then I did as dopefish suggested and changed XMMS' input and, just for good measure, I added a 2nd drive and right now XMMS is happily playing from both drives.

Thanks very much for your help.

As I said in my previous post, XMMS now plays happily from either cd-drive. However, it seems that some other apps are still a tad confused.

ripperx, using cdparanoia, complains that it cannot find /cdrom. Question is, how do I get /cdrom to point to /dvd - where my scsi-emulated ide-dvd is mounted/available/whatever? I've tried to symlink it, but after
--------------------
ln -s /dvd /cdrom
--------------------
ls -al /cdrom shows me this:
-------------------
total 3
drwxr-xr-x 2 root root 120 Feb 9 20:52 .
drwxr-xr-x 27 root root 680 Feb 9 17:46 ..
lrwxrwxrwx 1 root root 7 Feb 9 17:46 cdrom0 -> /cdrom0
lrwxrwxrwx 1 root root 4 Feb 9 20:52 dvd -> /dvd
lrwxrwxrwx 1 root root 9 Feb 7 16:57 scd1 -> /dev/scd1
--------------------

Any ideas, suggestions, hints?

Try making a link to your actual dvd device like
ln -s /dev/scd1 /cdrom
also try creating the link to /dev/cdrom
ln -s /dev/scd1 /dev/cdrom

Man this is weird. It still doesn't work.

This is the output of ls -al /dev/cdrom:
-----------------------------------------------------
lrwxrwxrwx 1 root root 4 Feb 7 15:57 /dev/cdrom -> /dvd
-----------------------------------------------------

and ls -al /cdrom shows this:
-----------------------------------------------------
total 3
drwxr-xr-x 2 root root 120 Feb 10 17:07 .
drwxr-xr-x 27 root root 680 Feb 9 17:46 ..
lrwxrwxrwx 1 root root 7 Feb 9 17:46 cdrom0 -> /cdrom0
lrwxrwxrwx 1 root root 4 Feb 9 20:52 dvd -> /dvd
lrwxrwxrwx 1 root root 9 Feb 10 17:07 scd1 -> /dev/scd1
-----------------------------------------------------

ls -al /dvd shows this:
-----------------------------------------------------
total 4
drwxrwxrwx 2 root root 168 Feb 10 17:07 .
drwxr-xr-x 27 root root 680 Feb 9 17:46 ..
lrwxrwxrwx 1 root root 6 Feb 7 15:57 cdrom -> /cdrom
lrwxrwxrwx 1 root root 11 Feb 9 17:46 cdrom0 -> /dev/cdrom0
lrwxrwxrwx 1 root root 11 Feb 7 15:58 cdrom1 -> /dev/cdrom1
lrwxrwxrwx 1 root root 9 Feb 10 17:07 scd1 -> /dev/scd1
lrwxrwxrwx 1 root root 5 Feb 7 15:57 scsi -> /scsi
-----------------------------------------------------
ls -al /dev/scd1 shows this:
-----------------------------------------------------
brw-rw---- 1 root cdrom 11, 1 Nov 9 16:01 /dev/scd1
-----------------------------------------------------

I'm really at a loss here. The way I see it, I need /cdrom and /dev/cdrom to point to /dev/scd1 or (maybe) /dvd. Should I maybe delete the various symlinks (how does one do that?) and create them from scratch?

As always, help is gratefully accepted.
