Are you asking how to recover videos that have been deleted by YouTube? Or how to download videos that exist off the site?

The former is impossible...I mean how could you download something that no longer exists.

The latter can be done through a large number of websites like keepvid.com.
 
OP, looks like you're SOL. YouTube has blocked public access to the video you mentioned, based on a copyright infringement claim by Apple. Keepvid won't work either.
