Eddie Izzard: Dress to Kill is my favorite

Sarah Silverman: Jesus in Magic
Jim Gaffigan - Beyond the Pale
Greg Behrendt Is Uncool
Henry Rollins: Shock and Awe - The Tour
Stephen Lynch - Live at The El Rey

and Dr. Katz is essentially stand-up acts in animated form

Richard Pryor - Live in Concert
(IMO, the greatest stand-up comedy show ever filmed!)

I would highly recommend any Eddie Izzard DVD. Dress to Kill (1999), as tasha99 mentioned, is really good, but Sexie (2003), Circle (2002), Glorious (1997), Definite Article (1996), Unrepeatable (1994) and Live at the Ambassadors (1993) are really no worse.

As an introduction, I wouldn't really start with Live at.., but anything else works really well. Note, however, that his later shows have touched more and more political and global issues, and so if you are not into that sort of a thing (although those issues are far from being the only thing he talks about even in his later shows), I would probably start off with the earlier stuff (say, up until Dress to Kill).

What I usually introduce to people first is Definite Article or Unrepeatable, and no one with a sense of humour has yet been disappointed.

Margaret Cho. I think she has about 3 or 4 DVDs. All great!

High agreement with the Eddie Izzard & Sarah Silverman recommendations. I'd also throw in the Jerry Seinfeld: I'm Telling You For the Last Time show. It's his standard material, but I thought it was a great presentation and send off. I think you can find it awfully cheap too, I grabbed mine from the Walmart bargain bin.

wow, you have "for what its worth" but don't have Killing them softly" from dave chappelle?

Also some George Carlin wouldn't hurt ya (Jammin in New York and Carlin at Carnagie are his best imo.

Katt Williams Live
Katt Williams Pimp Chronicles vol 1
Bad boys of comedy season 1
Kevin james sweat the small stuff

Eddie Murphy - Delirious

dennis leary and dennis miller were pretty good, tho i imagine most of their routines are out of date at this point.

Amen. You'll get plenty of play out of this one.

Lisa Lampanelli - Take It Like A Man

the funniest standup routine I've ever seen... I'm suprised I didn't shit myself I was laughing so hard.

FrancisRizzo3 recommended an excellent one...
"Stephen Lynch; Live at the El Ray"

def comedy jams

SEINFELD: I'm Telling You For The Last Time

And although it's a documentary about stand-up (it has a lot of stand-up in it), COMEDIAN.

anything that doesnt include Dane Cook.

Russell Peters!

I bought the Denis Leary disc last year, and it was just as funny to me as it was back in the day. "No Cure for Cancer" is still great and worth the price of the disc alone, and it also has "Lock and Load" and even a few extras.

Dennis Miller's better performances hold up surprisingly well despite his usually topical material. I have his The Off-White Album audio stand-up recording that's from 1988 (!) and it's still hilarious despite some dated topical references.

Eddie Izzard: Dressed To Kill, Comedian (not really a traditional stand-up dvd, but the commentary w/Jerry Seinfeld and Colin Quinn is worth the price of the disc alone), and my new favorite Gary Gulman: Boyish Man
