I genuinely don't recall ever seing any full background videos on product pages. Large embedded videos, sure.
There was tha fad many years ago for having fairly low quality, low contrast greyscale video set under halftone or pixellated filters to make the apparent quality better, but I'd still class that as not-so intrusive. They tended to be on multi media or 'design'-centric sites anyway.
