I read that this product will extract the LPCM audio track (5.1 or 7.1). Does it also extract the bitstream portion of the audio track so it keeps the DTS-MA and Dolby TrueHD (and ATMOS) tracks in tact? I currently only have DVD/BluRay Copy, so I assume I need to get this product to continue to back up movies without the Cinavia watermarking, correct?
