I think it can be done today with (modified?) video equipment. I do know that it's still done because I saw some new releases for this week in CD4 on one of the web-stores. I also wrote earlier that vinyl sales were up 30% for 2008. I since found that is was up 25% for 2007. I'm trying to find trends but there's little info and most of that is misleading. Like some audio-sector organization reporting that 100,000 turntables were sold in a year... one manufacturer commented that they alone sold more, so lots of figures are wrong. I do find that most vinyl production plants are at full capacity and extending. This finally got the attention from the big labels so who knows where this will go... ciao!
