This is just a gameplay vid of the PS1 version of Rayman 2. This is played on a PS2 with the texture smoothing on. I've heard there were some cuts made to this port of the game, but I'm not sure, because I don't own any other version. There is also added voice over tracks. I've heard mixed reports about what version is the best version of Rayman 2, the Dreamcast, or the PS2. I believe the PS2 port had extra content, but I don't remember for sure. Anyways, it seems that Rayman is now destined to be in a bunch of Mario Party clones instead of a true sequel to the platformer series. It's a shame really, but I guess platformers don't sell as well as mini-game games.
