I'm having the same issue here. Tried itunes "mp3 disc" option, roxio, nero,3 different brands of discs and all at 4x burn speed with closed sessions. Each disc has only given me "bad disc" (never worked). I tried burning and audio disc with the same media and that worked. So I was thinking must be something with the radio, but then I tried some mp3 books that my wife gave me. And the cds with the mp3 audio books worked. So now I know the radio read mp3 cds but can't find a combination that works yet. I'm going to keep trying different brands and programs, and report back. Hope someone out there figured it out already. Thanks
