I agree with all the previous reviewers positive comments, Diana at her best, the tracks, the musicians, the concert, the picture and sound are excellent. For a 'standard' dvd, the video & audio quality is outstanding, not only do I repeatedly enjoy watching and listening to it, but I also use it as a 'demo' for my home cinema set up. Both DD & DTS are crystal clear, the depth & dynamic range is awesome, ( put the crystal glasses away & make sure your neighbours are out!, when John Clayton plucks a bass string, your sub-woofer will love it, but they won't ! ). It's also 16:9 widescreen and picture perfect. I am an avid collector of music DVD's, and I also, have not come across anything close to this picture and sound quality, it gives Blu-Ray a run for it's money. This is a GREAT music DVD with an artist at her best and a superb visual, and 5:1 audio, recording, so if you only buy one music DVD make sure it's this one, and give your eyes a visual treat,and your ears and surround system a full blown Hi-Fi workout!.
