I have a Plextor DVDR PX-740A and I am having trouble making copies of my dvd of home movies and getting it to play on my old Apex dvd player. I can make copies of it on my old machine (Older Hewlett Packard Dvd burner) and they play just fine. Im curious of what might cause this problem, because Im stumped. I have tried numourous hours to get this to work with no success. The movies play on both computers, but just not on the old dvd player. Im using the same dvd-r's on both machines, so it cant be the type of dvd-r. Any help would be greatly appreciated guys.
