The Who: DVDs, Video...

I'm a big Who fan, although no one would know it from my DVD concert collection: nothing. Can anyone recommend where to start? I've seen half of the new Amazing Journey on TV, and loved it. Better than The Kids Are Alright, though? Should I go with a concert video such as Live at the Royal Albert Hall? While I was fascinated with the Amazing Journey documentary, it's the concert footage that I'm mostly interested in. I do want great video and audio quality, if possible, by the way. I'd also prefer widescreen, but if there's something great that is 4:3, I might have to re-think that.

Thanks
