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.

Quadrophenia should still be available on DVD widescreen.
It's not widescreen but very good. The Who, LIVE AT THE ISLE OF WIGHT FESTIVAL 1970. The DVD-V is 4.3, Dolby Digital, DTS and 5.1 2/3 of the disc is from Tommy. Pete did the remaster.
I have the Live at the Royal Albert Hall DVD and would highly recommend it. Picture and sound are excellent.
The Kids are Alright is indispensible for any Who fan and would my first choice. Theatrically released shortly after Moonie's death, it leaves off any Quadrophenia material but the DVD is in widescreen and the picture quality and sound quality(remixed for 5.1) are excellent. It contains complete definitive concert footage of Baba O'Riley and Won't Get Fooled Again from Moon's last concert appearance and features the Who's dynamite performance of A Quick One from the Rolling Stone's Rock and Roll Circus. The 2 disc special edition has an interesting bit on the extensive film restoration done for the DVD. It is a less comprehensive history of the Who than Amazing Journey but contains fewer truncated performances. It truly captures the sound and fury of the Who at their finest. Again, definitely my choice for a Who primer. Honorable mentions are as follows. Royal Albert Hall is also excellent with great 5.1 sound and widescreen picture. Also love Live at Isle of Wight despite 4x3 aspect ratio for its great performances, excellent sound and picture, and seeing the Who at their performing peak back in the day. 30 years of Maximum R&B is an adequate supplement to Kids are Alright. It covers a lot of concert material not contained in Kids such as Quadrophenia stuff, some old Marquee Club, a couple of songs from Isle of Wight, and some stuff from the 80's and 90's. Most of the songs are complete performances but not mixed for 5.1.
My thanks to everyone.

Jimburger, or anyone: The Kids Are Alright is a documentary, and Royal Albert Hall is a concert only? Also, 3 complete songs were mentioned with regard to The Kids Are Alright. Are there a lot more on it?
