A great concert indeed.  Actually, this is incredibly well produced  considering it was done in an arena and not on a soundstage.  If I have a  complaint, it is that there is no "center" channel sound in the  Dolby Digital-5.1 mode.  There is "center" channel in Dolby Pro  Logic, but to be honest "That Sucks".  AC-3 is the only way to  go.  If anyone has "center" channel sound in Dolby Digital,  please let me know.  I may have have a DVD with a glitch...
