My burned cd r/w or cd-r in mp4 format wont play on my sony dvd player and they won’t play on an older dvd player. They play fine on my Windows 7 (PC) but when I put them in the stand alone player it just says, “disk not readable” or “cannot play disK”--or other same such messages. Tell me what to do?
