When trying to rip a BD movie, for video I opt to copy original video, then for Audio I choose to rip the DTS-HD MA track only without recode. I have deselected all the other audio tracks. The resulting MKV file has the video, the DTS-HD MA audio track PLUS a Dolby Digital 2.0 track. Where did that track come from? This adds an extra step as I have to remux each MKV to remove the 2.0 audio track. Am I missing a step somewhere during the rip process? I have the means to play a file with HD audio only in it, I do not need to fallback track, thank you.
