Unfortunately, one of the greatest bands in the last 50 years has been given a lousy treatment on blu-ray. Live At the Paramount looks and sounds fantastic, but not all at once. The audio runs almost a full second ahead of the video. Sure, you could fix this on some home theatre receivers with the lip synch function, but IT'S NOT CONSISTENT. If you want to put this on in the background, or watch it with the sound down, or with your eyes blurred, or with 10 beers in you, it's grand. If you want to watch it and relive the experience of seeing Nirvana live, you'll be disappointed.
Edit: Apparently, there are a few copies that don't have the synch issue. As for the comment that anyone finding synch issues should "check their audio settings", I think that i can safely say that my audio knowledge and home theatre setup is competent at the very least. Google Nirvana Paramount Audio Synch....hundreds of people having issues is not isolated. Buy at your own risk, check out the amazon.com and blu-ray.com settings...amazon.ca issued an instant refund on this disc, which should tell you something.
