PDB does your analog track match the DVD or the WS LD on the staff drop? I've long been curious about that. Of course I just now went back and re-compared the two. The DVD has one sound of the stick hitting, and the LD has it roll around slightly.
The rest sounds the same but the WS LD mix has a potency that isn't in the 5.1. I don't know how to explain it exactly but it packs a lot more punch overall. Additionally the score has some directionality that isn't in the discrete version.
