Hi, Sorry yet another question. I've been recording my DVD's on DVD-R Grade A Mirror Platinum 4 x speed. They work fine on my PC and also on my DVD which is relatively new. I copied a DVD for a mate and am positive that I checked it was working. He has just called to say its not working - Could it be that his DVD player cant read this type of Disc or is it a Read Error from the DVD. When burning DVD's is it best to burn at MAX speed or is the slower the burn, the more accurate. As DVD Decrptor makes them all multi region I presume this wasnt the problem.
