Hehe

I finished listening to it and there doesn't seem to be anything we don't know about. Ancel just mentions Frédéric Houde as a really good coder, who was already working on console games at the time and whom he worked with for Rayman 1. They created a prototype for SNES together and sadly, that's all he says about the whole thing.
As for Rayman 2, I learned that Jacques Exertier did the art for Rayman 2 and then he (along with most of the R2 team) moved on to make BG&E (Jacques Exertier did the story!). It's likely that he's one of the big factors of what made those games so awesome!
It's also quite hilarious how he says they worked together on Rayman 3. The Rayman 3 team had to work on a different site than the BG&E team, so they decided to use webcams to communicate with Ancel and other team members to "work together well". In the end, they, as he says, "argued well". The R3 team showed them animations and other stuff and they ended up screaming at each other that it was horrible, over the webcam.
EDIT -> Lol, I just realized I have already seen this in the past. Here's the original:

As I translated before, the final RRR is actually mostly the result of a rushed presentation for a journalist of Nintendo Magazine. Because they had presented a minigame collection so they would appear to be using the Wii controls to their full extent, they had to go with the minigame idea instead of the platformer. And that's how it happened!
Also, the bit in the beginning with his 2 sisters was funny.
