A little help

i bought software that allowed me to copy my digital pictures to a cd and play them in my dvd player and display them in a slideshow on the tv screen.
the slide show works fine on either a cd-rw, a misic cd, or a cd-r, but the muisic is distorted on all three when the slide show begans to play.
i followed the guide in the software about attaching a mp3 music file to the slide show,(copy it to the hard drive, right click and “add audio” into the slide show).
but it still is distorted.
can any body offer a little help?
it will be appreciated…thank, m. allen
