After I rip a DVD, I use DVD2AVI to extract the audio file. It is saved as a wave file. My problem is, when I play my DVD in a stand-alone player, it recognizes the sound as analog. Why does it not recognize the sound as a digital sound? Why not pcm or sound form of digital? My digital receiver can auto detect DTS, Dolby Digital, PCM, and analog. I thought that it would at least recognize the sound as PCM. I have also used Smartripper with the same rsults. Am I doing something wrong?
