I tried out several audio protected cd's with my 40w back when I got it in may. I couldn't read any of them. After overclocking to the 48W VS02 firmware, I tried the Celine Dion - A New Day Has Come. This has Key2audio protection. The CD was recognized and I could extract the files. Seems like the Liteon people are doing a great job. Any others that have tested protected audio cd's?
