the picture quality of the Brazilian DVD "Acustico" is actually quite good. I've had some more DVDs from that company which were obviously copied from some LaserDiscs. The best of them is the MTV gig. Don't hesitate to buy it. Dietmar

However, it looks like VHS or dodgy Betacam transfers.  The sound on my Page and Plant DVD is 5.1, and not bad, but the picture quality is awful....  I think the Sting unplugged DVD is by the same company - though I haven't bought it, so can't be 100% sure.
