The links you are using are not "official" but from a fan-made site. A very good one btw, from our very own member Ustas.
I can't help you, sorry. I would guess everything has seen the light of day already...
A clip I never found and saw again was from that OES Dire Straits MTV Weekend, where they were rehearsing "Planet of New Orleans"... with a quite long guitar sequence... Is it stuff like this you are referring to? Our AMIT TV might be a good scource for you, too!
