I'm sure it is just a UDF file system.  That is supported under Linux, it
just may require a kernel recompile.  It is under:

File-Systems-->UDF File System Support (read only)

in make menuconfig for the kernel.  The help says this:

  ? CONFIG_UDF_FS:                                                          ?
  ?                                                                         ?
  ? This is the new file system used on some CD-ROMs and DVDs. Say Y if     ?
  ? you intend to mount DVD discs or CDRW's written in packet mode, or      ?
  ? if written to by other UDF utilities, such as DirectCD. This UDF        ?
  ? file system support is read-only. If you want to write to UDF           ?
  ? file systems on some media, you need to say Y to "UDF read-write        ?
  ? support" below in addition. Please read                                 ?
  ? Documentation/filesystems/udf.txt.                                      ?
  ?                                                                         ?
  ? This file system support is also available as a module ( = code         ?
  ? which can be inserted in and removed from the running kernel            ?
  ? whenever you want). The module is called udf.o. If you want to          ?
  ? compile it as a module, say M here and read                             ?
  ? Documentation/modules.txt.                                              ?
  ?                                                                         ?
  ? If unsure, say N.

That sures seems easier than a trip to CompUSA. :-)

Try: (probably as root)

mount -t UDF /path-to-cdrom /path-to-mount-point.

If it compains about not knowing UDF, recompile it into your kernel.
Then that should work.
