Production values are extremely high: it's a widescreen presentation shot on high-def video and nicely mixed for multichannel Dolby Digital 5.1 surround sound (with a thinner, collapsed version of the same for Dolby 2.0). It must be noted, however, that the center, subwoofer, and surround channels get jumbled right at 1:35:30 on disc 1. The front left/right channels remain in place, but the signals for the other four speakers play non-musical chairs. People listening in 2.0 will experience a brief dropout at that point. --Michael Mikesell
