The answer is yes. A few years back, the "Sunday Morning Show with Charles Kerault (sp?)" showcased a carnegie hall performance with Arthur Papazian (sp?) playing all 24. You could probably contact CBS television for an archived copy.
As for Libetta, let's see... it's now 2004. Where is the video?
Meiting, I know the Godowsky studies intimately. Now listen, my friend: only SOME Godowsky etudes are not worth much musically (ok, MOST of them), but don't discount all of them. Audiences love them, especially those who are obscure piano-freakes, and they offer fresh insights into already great music. I know eleven of them and I have played them everywhere, including Carnegie's Weill Hall. People have asked me if I will learn and record them all at some point. My answer is no, because SOME of them are not interesting musically, and my hands are too small to play some of the Left hand ones without rolling everything. You should give some a try. I chose to play the ones that have the biggest musical payoff, and I'll probably learn a few more, but give them a chance. Plus, they can take an already great technique to greater heights. Which ones did you play?
