The above video, titled Internal - Apple Authorized Service Provider 101 appears to be from 2007 (some things might have changed since then).

It will be interesting to see if these videos get taken down by Apple.
In the meantime, have a look and you might want to download these locally if you like them. A bunch of other videos on his Youtube channel and below:
