YouTube is not only using googlevideo domain. That domain is for the
video itself, but many other parts of the visible page and pieces of the
vidoe layer and TLS dependencies use other Google owned or hosted
domains. All of that can use hundreds of objects not in *.googlevideo.com.

There are other things too. But I dont have time right now to write that
up. You can use debug_options 11,2 to see the HTTP message headers and
figure it out.
