This review is to add a few observations to the general consensus, with which I agree. No one should be dissuaded from purchasing this because I give it, in effect, an A rather than an A-plus.
Maazel lets the music speak for itself. Nothing is over-dramatized, and there were times that I missed the extra punch that some conductors (Solti & Szell, for examples) have given various phrases. The orchestra, not unexpectedly, played gloriously. Oddly, the Philharmonie Berlin was not filled to capacity for this event.
The remainder of my comments deals with the technical quality of the audio, video, and authoring of this Blu-ray disc:
I first have to express surprise that this 2000 performance was captured in HD--I didn't know it went back that far. I would not have been surprised if this were a film transfer since 35mm film is inherently HD, but this is a direct-to-video recording, and it is quite detailed.
The audio, wonderful as it is, could have been better. This may be the only time I have preferred the LPCM stereo track to DTS-HD-MA, the latter adding almost nothing to a sense of space, while slightly muffling things, especially the first violins. The volume adjustments and balances in the microphone mix from the various sections of the orchestra, while too subtle to notice in themselves, had the overall effect of preventing crescendos and climaxes from reaching their full dynamic potential.
The Blu-ray mastering is slightly botched in several ways: (1) in spite of the disc's relative austerity of features, it seems to have been authored with Java, unnecessarily slowing its load time. (2) The authoring language prevents any kind of resume capability should you turn the player off; likewise, there is no bookmarking feature, although one can resume by going to a specific chapter from the menu. Along with this, the disc provides the player with no memory of its audio setting, should one happen not to listen to all of it at once. (3) Time, chapter, and title information are not made available to the player for display either on-screen or on the device's on status window. All this makes it rather inconvenient to divide one's viewing of the 75-minute performance into shorter listening sessions; but considering that the cumulative effect is greater when hearing it all in one seating, these limitations could be considered a good thing. Certainly the audience gets few breaks in the Ring operas themselves, Das Rheingold, for instance being one 2-and-a-half-hour bladder-testing act! Better though, to give the home-theater audience a choice.
I hope that these comments may be of interest to some and that they may somehow filter through to EuroArts, who needs to clean up their act a bit, although I must express profound appreciation to them for stepping in where DG, London, Philips, EMI, & Sony have all failed, namely in providing an adequate number of classical-music Blu-ray releases. From that standpoint, and others, we are very lucky indeed to have this disc.
