I'm wondering if the CD is in a file format that has been removed from

Well, I think the problem is KDE now. I manually mounted the original CD
using:

sudo mount -t iso9660 /dev/sr0 guitarws2nd

Where guitarws2nd is a directory in my CWD.

The CD mounted. If I ommit sudo or "-t iso9660", then it get the same
errors as before.

actually this is what I originally suggested - I must not have been clear.

in your post preceding this one, you were trying to mount an .iso file. I
I don't recall iso files being mentioned before; to mount such a file you
use the '-o loop' syntax but not the '-t filetype' syntax.

you might have a look at 'man mount'.

if you are mounting the cd itself (as opposed to an .iso file), then you
use the 't filesystem' syntax. '-t iso9660' is the standard file system
for cds. (do not add '-o loop'!)

have a look at 'man mount'.

you need 'sudo' because it is an operation done by root.

I don't know what problem you are having with kde. you will have to
explain that a bit more. once mounted the cd should show up on the desktop
somewhere and you can click the icon to view it.

Thank Felmon. My first post was about mounting the CD itself. Well, I wasn't
mounting the CD, I was waiting for KDE to do it for me and open Konqueror
window (just it does for all my other CDs). When the window was not
appearing, I checked dmesg. That's when I found those errors. From there, I
tried the following:

1. Rebooting into Vista and inserting the CD into the drive. The CD worked.

2. Using Roxio (didn't even know I had it) from within Vista and made a copy
of the CD. That CD-R worked in Vista but not in openSUSE. I got the same
error messages.

3. As suggested earlier in this post, I used k3b to create a CD but I ran
out of CD-Rs, so I made a .iso instead. I had to set k3b to make a raw
copy. If I told it to a normal copy, k3b would freeze. Once the .iso was
created, I think right-clicked on the .iso, in Konqueror, selected
Actions->Mount ISO. I entered the root password. The ISO still failed to
mount with a non-descript error message dialog (i.e. failed to mount ...).

4. Using the mount command that appeared in #3 (above), I tried mounting in
the console. Turns out mount complained about the filesystem ("mount: you
must specify the filesystem type"). So I added "-t iso9660" but that still
didn't work:

mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

5. I gave up on the .iso and tried again with the original CD. I did:

# mount /dev/sr0 /mnt/guitarws2nd
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: you must specify the filesystem type

Then I added the iso9660 fs type:

# mount -t iso9660 /dev/sr0 /mnt/guitarws2nd
mount: block device /dev/sr0 is write-protected, mounting read-only

And the CD mounted! I can go into the /mnt/guitarws2nd and use wine to start
the software. This is what I get from dmesg after the successful mount:

ISO 9660 Extensions: Microsoft Joliet Level 1
ISOFS: changing to secondary root

I have no idea what the "secondary root" is, but I suspect that is the
problem?
