One of my recent threads was on spam sites beating Google sites in the SERPS, so they look like they have been neutral so far.
I have seen maps get a special ranking, but not Youtube videos - what I see is a video results section on the SERPS that can have video from other sites, but which gets dominated by Youtube, presumably because Youtube dominates video hosting.
Google Books already carries Google affiliate links.
