Cant burn cd's sucessfully

Im using creative mediasource organizer and made my cd’s in the past without a problem. Now, after I burn the cd and place it into the home stereo…the only sound is a high pitched squeeling one. The only thing Im sure that’s different is I reinstalled windows xp media a few weeks ago, and my son also downloaded some songs from the library to his cell phone.
Does anyone know what I might troubleshoot or try here?

It doesn’t sound like you are burning the discs in audio mode. Playing data CD’s on a home stereo creates a squealing sound as you describe and it can be harmful to your hardware…and ears.
