Audio CD Protection doubt

Hi to all,

I’m using the Clone Audio Protector 1.1, which has the SYS Protection and the Cactus Data Shield in order to protect the audio CDs. My problem is that the protected CDs can’t be listened in DVD players. I’ve tried to edit manually the CCD image file created by CloneCD, changing the PMin, PSec, PFrame and Control data but the result remains the same. Is there any way to protect de Audio CDs that allow to be played in DVD units?.

Thanks in advance.
