If you, like me, are a Linux user who has picked up the Rush - Snakes and Arrows MVI disc, you may notice that you're missing the mp3 files, the wallpapers, and the buddy icons that should have shipped with the disc. Never fear, intrepid traveler, its still there on the disc, but the automounter isn't picking the correct format for the disc. In order to get at all of the golden goodies, try the following:

sudo umount /media/cdrom

sudo mount -t udf /dev/hdc /media/cdrom

where /dev/hdc is your device, and /media/cdrom is your mount point. This will get you to the content on the disc. You'll still need a Windows or Macintosh machine to get to the online content (or at least I'm not aware of any way to get to it just under Linux) but this will at least allow you to get access to what's on the disc. You'll also be able to use this method for the other MVI discs, like Linkin Park's Minutes to Midnight, and The Flaming Lips new MVI album.
