Whenever I try to play a DVD-Audio in PowerDVD I get a pop up saying “CPPM must be activated before playiny CPPM-protected cntent. Please connect to the Internent and press Ok when ready”. So I do what I tells me to and I get the same pop uo over and over.
I have exactly the same problem with PowerDVD…
I tried with DVD-A of Linkin Park - Reanimation. Yours was the same DVD?
I get it with any DVD-Audio disc.
Did you try with WinDVD 6 Platinium ? It seems that it has a DVD Audio playback feature.
