I was excited to see this release but after seeing the set list, I wasn't so sure I wanted to buy it. Thanks to Netflix, I was able to watch this one this week and I'm kind of glad I didn't just go out and buy it for exactly my original concern: is it fresh enough to warrant a purchase? The set list is different enough from the previous Live in Paris DVD, but still fairly typical of one of her sets IMO.
The video seems to have some grain to it at times, on what appear to be very long distance zoom shots, but overall the video quality is quite excellent. The shots of Rio itself are absolutely stunning HD video.
The Audio quality of the dts-HD track is also a bit odd in that there were some times where it seemed like I was missing something. I could see her sweeping the keys, but I didn't here that sound as obviously as I would have expected. Then at other times, you could hear the faintest of sounds as she move the mic or adjusted something or made comments away from the mic. I was impressed with the envelopment of the overall track and her voice sounds as lush or luscious as I expected.
There are a few excellent extras as well, with Diana doing a small unplugged session in a local restaurant. This was almost better than the concert itself, and is practically worth the rental alone if you are a fan.
This one is good as expected but manages to feel like a bit of the same. I enjoyed it, but I would say rental only on this one unless you are a huge fan of hers.
