Download good quality advertisement clips - From where?

[sling-shot]

Due to some or other reason we will like some of the ads that run on TV channels. We may like to save them.

Presently I use YouTube or rarely the original advertiser's site (not the ad agency). But invariably they turn out to be lower quality videos compared to what is seen on TV.

Is there any source unknown to me from where I can get at least DVD / broadcast television quality ads online?

Since this is a topic on adverts..

anybody remembers the Adidas ad featuring Sachin practising his cricket shots in an empty stadium? it would be great if anybody can link me to that ad.
