I have a lot of works on three and even four CD. I know a lot of people that have had multi CD albums of just one work. Operas and Bach's St. Matthew Passion and many others come to mind.\nBDs are wonderful as you get a picture and long works on one disc.\n\nI know, Mark, but long classical works, or even recordings of pop music concerts (which often run two hours or more) are rarities in the music world. I'd guess long classical works sell better in Europe, but even there I doubt the total sales come close to justifying the support of a new format. You know as well as I do this is a business question, not a technical one.
