I bought it. Haven't watched the DVD yet, but I've listened to the CD a few times through. Great mix. I really love their cover of Korn's Thoughtless.
On a side note, I saw them in London over the summer and I heard the DVD show got down to that show or the Paris one. Sad to see they went with Paris Either way, it's the same set and I thought it was pretty solid.
I watched two songs on the dvd. It's a good mix but the LFE is really high. I have my system calibrated with VE and the Sub is at about 78db. It thumped so much that it drowned out other sounds. Otherwise it's a good disc.
The audio on the DVD and CD are different. The LFE on the DVD is outstanding but you'll have to adjust it a tad. I have an SVS20-39 and it's the best concert base I've ever heard.
The actual concert video . . .well . . .sucks. You never really get a clear shot of Amy or any of the bands. I thing the editor had ADD or something and could not focus one train of though for more then 2 seconds.
With that said - I think the Audio is outstanding for a life concert. The 5.1 (or 7.1) does a pretty good job.
I have not watched the extras except for the music Vids (where do people watch Music Vids anymore???)
Bottom line - for ME - it was worth the money and my SVS20-39 rocks the house!
