Question: I have my home movies (uncopyrighted) on finalized DVD-R disks.  Can they be used as the source disk?
Document: I tried to copy a DVD I made with footage I shot myself. (No copy-protect issues. )Used a clean, erased +RW as target. Did not copy.Called tech support (they are very nice, by the way).I was told that RW discs could be a problem with this model (that's not what the product description says).I tried a brand new -R disc. Did not work, the machine spun endlessly. Could not eject the discs. Had to shut off the power supply and then power up again.The machine ejected both discs, but the target disc was damaged (scarred the recording surface).Waste of time.
I put this right to work after I got it. I had to copy 25 CDs and it did the job wonderfully fast. This is a great tool and would recommend it.
IT DID NOT WORK so I can,t give a reveiw, it was a gift to someone so I was disappointed it did not workmy friend wanted me to order another , I will only order for myself for now on .
