I picked up this set on behalf of my dad as a Christmas present to me. I've only dipped in today and checked the surround part of the discs worked and played little bits out of intrigue. No full tracks, and it shouldn't be much trouble to wait until December. I've got to say though that the attention to detail on the sleeves is lovely, and the disks are authored so conveniently so they play straight off in quad, no button pressing.
