By the way, among my soundtracks, I have a CDR titled "Indiana Jones and the Forbidden Eye". It's a boot with a recording of the score and dialogue used in what, I've read, was an Indy-themed rollercoaster ride in the DisneyLand. It's boring and not at all memorable (and, musically, it mostly recycles Williams in questionable quality and with bad editing), but if there was some space to use on the DVD-Rs, it might make an Easter Egg...

As for the isolated movie scores, I would not bother with those, personally... They would be of interest to us score collectors only, and I can assure you that any self-respecting score collector already has the expanded Raiders, the 2CD Raiders bootleg, the official Temple, the fan 2CD Temple, the official Crusade, the "Lost Crusade" and the 2CD Crusade bootlegs (and probably more - I think I have all Indy soundtracks in existence, even those mostly pointless, such as all game score rips...)

Using up space for them on those discs would be rather redundant...
