I dumbly bought a 25 pack of cd-rw's thinking they would be perfect for burning music because when i don't want the music anymore i could just re-do the cd. well I tried copying a cd-r onto a cd-rw and the burn was successful and all but the cd will only work in my computer, my cd player and my discman both say no disc. Cd-r's work in them though. I use Nero 5.3, and my burner is a 4x. The Cd-rw i am using is a Memorex 4x... Please help, I know it may not be possible for me to some how format the disc to play in my discman and cd player but hey it doesn't hurt to try. I appreciate anyhelp you can give me.
