17. Can I decrypt/rip a DVD-A (DVD-Audio) disk? What format does DVD-A use?
 
DVD-A uses either LPCM or a lossless encoding called MLP (Meridian Lossless Packing), and supports up to 24 bit and 192 KHz audio. Due to the strong encryption of DVD-Audio, there is no way at this time to decrypt DVD-A disks.
 
One possibility for extracting the audio would be to attach the S/PDIF out of your DVD-A player to the S/PDIF in of your soundcard. Due to the strong encryption of the DVD-A format and the extremely high cost of MLP decoder licenses, there may never be an ideal solution for ripping DVD-A.
