IF IT SOUNDS POOR, IT'S YOUR OWN FAULT: There have been a lot of grumbles from people who've lashed out their granny's life savings on the most recent Bowie DVD that the sound quality is poor, all of which have been waved away by Tony Visconti. He says - and he's not wrong - that because there are so many competing systems and possible settings and so on, it's up the purchaser to tweak their menus to make the thing sound decent. But while he's not wrong, it's hardly very encouraging telling people that the chances are, before they can play the thing, they'll have to spend ages fiddling about with settings, is it? Even in the 70s it was check you've got the right needle - stereo or mono - check you've got the right speed, and away you go. Here we are in a brave new age, and you're lumbered with a short session as a computer programmer before the first track. Still, at least there's only one standard of DVD at the moment - how fun will things be when there's the current type as well as two new formats bobbing about?
