Overall the best concert/documentary DVD I've seen is The Who - The Kids Are Alright. It has recently remastered DD and DTS 5.1 soundtracks, and is in wide screen format. Some of the performances are breathtaking, esp on Axiom speakers. http://www.amazon.com/exec/obidos/tg/detail/-/B0000AFQS0/qid=1079653149/sr=8-1/ref=pd_ka_1/104-4895577-5237568?v=glance&s=dvd&n=507846

It's unfortunate many other bands of that era weren't recorded in equal fidelity.
