Well, you did not trawl Queenzone and not Dimeadozen, because the Brixton DVD was shared on both sites http://www.queenzone.com/queenzone/forumnew/forum_topic_view.aspx?Q=520243
Whenever a DVD or new concert is shared on QZ or DAD, there are a couple of people who grab it just to make money from something they downloaded for free from the net. I know that there are enough customers who are unfamiliar with the concept of sharing, torrenting, hub etc and they are happy about the ebay sales.
But those who share the material and those who actually recorded/filmed the concerts are definitely NOT happy about such ebay re-use of their generously shared material.
Therefore many tapers stopped sharing their recordings on QZ or DAD which is a shame but understandable.
I do not want any google ads here.
