My only complaint about the DualDisc was that Jons vocals were a tad too high in the mix. Even when I did my downmix of the 5.1 extended version. I should probably redo that but before I do the actual downmixing perhaps load the centre channel into Audacity and lower it down.

Also, New Jersey: Deluxe Exition could have included a 5.1 surround sound mix, if one actually exists. Imagine "Lay Your Hands on Me" in true surround sound.
