Thank you, Bret.
I understand now, and you are correct. I was given the 5.1 tracks, and not the stems, even though I asked for stems (as this was my experience with stereo sound in the past)
I can definitely ask for *the stems* again tomorrow. Or should I work with these channels? What would be the proper workflow cutting down a 5.1 video into a 5.1 trailer?
I apologize if my questions are very simple; audio is not my forte.
