Good :) The fmt=18 ones appear to be h264 .mp4's 480x360, being played through flash. It is possible to download them, they may be the same versions curently being used on apple tv or iphone/ipod touch youtube feature, not sure.
The fmt=6 one (of the dog skateboarding at least) appeared to be some sort of higher quality .flv, I havent tried to work out what codec or res.
