Until about 6 months ago, I could burn audio cd's easily with Microsoft Media Player on my computer with WinXP home edition. Now I can only make audio cd's that regular cd and dvd players don't recognize. I've tried 3 or 4 different programs, still they won't play. My CD-RW is about 3 years old and is 40x max.speed. Have used 2 brands of blanks and still nothing. What could be wrong?
