I have a Pioneer 656A which plays my DVD-Rs just wonderfully. Most other players won't. There is a reason behind this: Whenever I started burning my home videos to DVDR a year ago, I was using Nero. There are two ways of burning the DVD : DVD/ISO or DVD/VIDEO. I had always used DVD/ISO since this method was the first on the list, and they played fine in my player. Little did I know that the Pioneer player was one of the few players that would play DVDRs formatted in the ISO mode. So my question is this: Can you burn a DVDR using Nero, in DVD/ISO mode and try it on your Pioneer 563 player? I would have to order the player online and want to confirm that my collection of DVDRs will work. If you don't have Nero, a trial version is available online at www.nero.com I can even paypal you the 1 or 2 bucks the DVDR may cost you to burn. I would really really appreciate the favor, if any one run this little test for me! Marc.
