My Eagle-Eyed colleague Cdanteek elbowed my ribs to point out that the Sony is a +/- drive too [I misread the specs I was referring to, muy bad, my apologies, need coffee!] however that doesn't change the recommendations. I have copied a DVD- to a DVD+ blank and vice-versa without problems.
I can't see why both drives are rejecting your blank discs, though. What brand/speed are the discs?
If you're getting a proper read on the source disc, may I suggest you use the
Copy > Save Image part of the menu to save an image of the DVD to your hard drive, and then use Copy > Burn Image to Disc to try and burn the thing as a separate operation.
If you can, save it as an ISO file so that if 'Burn Image' falls over and spits the disc, you can try burning the ISO to plastic with the ever-reliable and simple free download
ImgBurn.Please let us know how you get on. This has me intrigued.
