Welcome to CDRLabs, Kundo!
How fast is your computer, and how much RAM do you have? If your processor is less than about 1-GHz, you probably won't be able to burn CD-A at 52x from MP3 files.
Also, you might want to try some different discs. Some CD-A players are very picky about the brand of discs you use. Have you tried playing the discs in your computer, or only in a CD-A player?
