Windows Media Player has a built in Pitch Control so that might be one of your problems right there. Try downloading the newest version providing your computer is Windows XP with SP 2 or Vista. Another thing could be your CD burner drivers are outdated or messed up. The 2 biggest companies are Roxio and Nero and 80% of all CD or DVD burners will have a OEM free version of this software.
