Are they AUDIO CD's or data CD's?
I have had problems burning waves to data CD's in the past.
I asked a computer guy I knew and he recommended getting the Audio specific disks....and they worked just fine. He explained that there's something in how they make the disks or some other mumbo-jumbo that sometimes the data disks work just fine for music and sometimes they don't....all I know is I now use audio CD's and there's no problems.
Herb, audio CDs are silver on the recording side. Music CD players like silver. Some data CDs are other colors and many don't play on some CD players.
Been there - done that.
