I recently purchased Nine Inch Nails "The Downward Spiral" on DualDisc. In this case, the DVD side does contain high resolution mixes. However, on my Denon 3910, the CD side skips on the last few tracks.

If DualDisc provides high resolution content...I like the format. However, if the DVD side is used to provide a few videos and interviews instead of high-rez mixes, I am not interested in it.
