Blizzard hasnt released any videos for SC2. Thus, these are currently videos of a third party maker setting on foot on SC. Illegal.
Well, I don't know if they're illegal or not, but they certainly aren't
official.QUOTE
If you mean the C&C mod, that's old, and it was shut down like over a year ago =/ The WCIII Mod seems to be legal, as it requires both games to work, they havn't released any video or anything yet. Still a work in progress as far as I know.
Yes, I think they were very careful to make sure they weren't violating any of Blizzard's legalese. Of course, Blizzard could probably still shut them down if they really wanted to.

The original terran campaign had 12 levels. However 2 were thrown out. It's believed because Blizzard wanted 10 levels for each campaign. the 2 levels CHK's can be extracted and played though.
How? I might like to have a look at them, if there's some easy way to do it without being a l33t h4xx0r.
