Question about Videos on

I have a question about the videos on Do you guys think the videos are hosted on his site or just an embedded link?

If it an embedded link, which program is he using, and is there anyway to find out the source of the link so I can grab the embed link myself?

If the videos are hosted on his website, would it be costly to do the same and host videos of that length and quality?

Sorry if this is posted in the wrong section, I was not sure which section would be most appropriate.

Thank you.
