Professional machine made by US DigitalMedia (cdrom2go.com). They have references to this model online, but I don't know if they still sell it direct any more.
I used to be an in-house video producer for a large corporation and so we copied DVDs to send out to all the branch offices with this. Worked superbly. Anyone who is doing mid volume DVD copying onto blank DVD-Rs (also does CDs), this machine can do the trick. It makes an ISO from your source disc and stores it on a hard disk inside. Then you can burn up to 5 optical discs concurrently at up to 16x speed. I have never had a failure with it. Ask for Erik. Best is texts, next is calls, as for emails...good luck. :)
