I hope this isn't old news but I stumbled on the following article:

Now you can legally and free watch full episodes of South Park online.

Just go to http://www.southparkstudios.com/
and use the Episode Guide to get more info or watch full episode.

This works relatively well with my N800. Video and sound quality is quite good.
Screen update is little slow but it is watchable.

Enjoy.
