i don't know about VHS, but the New Barbarians DVDs i know of are:
~ Buried Alive: the Largo gig, which is a good show; i'd give it about a B or B- in terms of audio/visual quality.
~ Seven Days: part of the San Diego gig and most of the Barbarians' Knebworth Fair appearance. the audio/visual quality's pretty raggedy (about a C, i guess) but the performances are really special, in more ways than one. :E i get a lot of joy out of it - but then, i just freakin love the New Barbarians.
~ a two-disk set (a Jointrip production, i believe) called The New Barbarians 74/79. disk two is the aforementioned Largo 79 gig; disk one includes part of one of the Kilburn 74 shows by Ron Wood & Band (known fondly in some circles as The Baby Barbarians: Woody, Keith, Ian McLagan, Willie Weeks, Andy Newmark) (oh and Rod Stewart too, for two numbers) - that is some fine cookin! the disk also has assorted clips related to Keith's sentence and the CNIB benefits, including some nearly indecipherable fragments of the concert.
hope that helps (and sorry i don't have DVD-copying capability) ...
