I can watch a Netflix movie in 3G at 320kmh (TGV, in France). So you're right, video consumes fewer bandwidth than we imagine. But it's common that I can't view a proper Youtube video on ADSL. ISPs are really being deceptive when they provide a connection to "the Internet".

It's a well known fact that certain ISPs in France will not peer with YouTube and thus their connections are congested.

This is not a technical problem, but a business decision. The at only solution is to vote with your wallet and chose an ISP that sucks less.
