I would appreciate being pointed in the right direction on making backup copies of all my 5.1 stuff: SACD/DVD-A/Dualdisc. I’m sure there’s a thread here for someone who isn’t a computer wizard. If there was a business offering this I’d gladly play, but most A/V conversion shops in Phoenix know nothing about 5.1 formats. In a perfect world, I could make a backup disc, of every format I have, in DTS or DVD-A (I can play DVD-A/DTS in the Acura). Can someone point me in the right direction? Thanks.
