Query: Great 5.1 DTS audio mix

I was surprised how great the 5.1 mixes sound (if your stereo system supports 5.1). Both the 5.1 Dolby and 5.1 DTS mixes are superior to the 5.1 sound on Blondie's last live DVD. And that DVD sounded great.Jimmi Destri the keyboardist is missing, which is a bit disappointing but his replacement is fine. Debbie Harry sounds in top form and there is no evidence she is lip-syncing, which so many performers will do in "live" performances. I suspect she had a face and body-lift recently. She looks great in any case.
