I'm choosing a video codec for storing of my family videos (and sharing some of them in the Inernet as well) which format provides the best compression? I don't care about processor time and the quality should be avarage or just below (I have a cheap cam)

you cant beat the price anyway.

edit: just playing around, here is a random clip from my disk encoded with 100 kbps (that would be super-low-bitrate), mute:
