I have a CD of a commercial software program that I am attempting to run
under wine. The CD works without problems under Windows, but when I mount
it on linux the file system appears to be empty (no files or
directories). The drive is capable of reading the CD because "strings
/dev/cdrom" works.
What would I need to do in order to troubleshoot this problem?

Firstly check what occurs if you mount it by hand with -t iso9660 and
with -t udf. Secondly check dmesg for any diagnostics from the mount such
as corrupt metadata on the CD.

Maybe try mounting with the "-o unhide" option. Or maybe it is a
multi-session disc?

It will not mount as UDF:
UDF-fs: No VRS found
UDF-fs: No partition found (1)
As iso9660:
mount -t iso9660 /dev/cdrom /mnt/cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
dmesg:
ISO 9660 Extensions: Microsoft Joliet Level 1
ISO 9660 Extensions: IEEE_P1282
I tried this on three different machines all with the same result.

-o unhide does not help. Can a factory-pressed disc be multisession? It's
not a CD-R

Could you post the header part of the cd? ie:
dd if=/dev/cdrom of=header bs=1k count=32

Sorry, my mistake, getting the meta data we need at least 64k.
Could you send again the header?
dd if=/dev/cdrom of=header bs=1k count=64

So it must be an apple hfs disc, (or hybrid disc?).
Maybe you may try mount it as hfs, this problem is not relevant to iso9660.

Yes (for example "Enhanced CDs" which contain both audio and data
tracks). I think the default on MS Windows is to mount the last
session on the disc. You should be able to use mount paramater "-o
session=x" with x being the session number you want to mount.

I can mount the disc as hfsplus but it shows the OS X contents instead
of the Windows contents.

Looks like Rosetta Stone :) and i think it is hybrid HFS/iso9660. I
can see windows-related filenames in the sample you uploaded, so we
know they are out there somewhere. Maybe try this in your mount
options (thanks google):
mount -t iso9660 -o norock,map=off
Also, if that doesn't work, do you have CONFIG_JOLIET=y in your kernel
.config? Maybe it's needed...

I have tested this disc on my Windows XP machine at work and it has no
problems reading it. The program supports Windows and OS X so it is probably a
hybrid disc. I can try mounting as hfs at home tonight as well as extracting
the rest of the metadata.
If I am able to mount as hfs I don't know how much good that will do unless it
is possible to run OS X programs under linux.
