Yes, turns out I have them in both formats (MLP and AC3) from the same DualDisc, I expect they would be the same mix. Besides the Britney, what other DualDiscs have a separate DVD-A (or SACD), released at different time?
they're the same mixes across the board but there were a number of DVD-A DualDisc releases of titles previously released on Surround SACD by Universal, incl.
- Diana Krall "Girl In The Other Room",
- Dire Straits "Brothers In Arms",
- Jamie Cullum "Twentysomething",
- Keane "Hopes and Fears",
- Lee Ann Womack "Greatest Hits",
- 3 Doors Down "Away From The Sun",
- Mark Knopfler "Shangri-La",
- NIN "The Downward Spiral",
- Sheryl Crow "The Globe Sessions",
- Snow Patrol "Final Straw",
- Toby Keith "Shock N Y'All"
edit: i should add, in all but the Knopfler/Dire Straits cases where the subsequent DualDisc release was on another label (Warner), the DualDiscs listed were UMG releases.
