Actually no, unless the DVDs player gets installed with drivers. But it seems now everything is all plugin-n-play, without the need to install drivers.
I tested one of our sample animation DVD on one of our renderfarm computers with no DVD player, just windows media player (windows Xp). Windows media player prompts a missing codec (mpeg2) which you have to purchase.
Using a particular hollywood movie DVD, it runs (but not through windows media player). It seems it uses a player that comes with it (interactual player) - not sure if they are all like this.
