Ok, i have a PHILIPS DVD+-RW SDVD8820 AD15 dvd burner on my computer and i use Sony Verbatim DVD-R's. I use the program AnyDVD and CloneDVD 2. When i try to copy a movie for a backup it will not play on the dvd player. Some will and some wont (the movies i use have already been ripped, so its not like a auctal DVD). On Clonedvd i use Clone DVD, then the thing beside quiality is DVD-5, in the next section i select everything, then in the next one i select DVD Writer. I thought maybe it was AnyDVD messing it up, so i closed it and tried burning it.. still doesnt work. When i put the dvd in the player it doesnt read it, and keeps trying. Ummm, not sure what else to say i tried to explain the problem the best i could.. if u need to know any more information just ask.
