Hi Noah,
My “Thank You” and my “Apology”. “Thank You” for the smudge suggestion. I immediately looked at the back of the DVD. Fingerprint smudge visible. Smudge removed. DVD put into old (Circa 2001) DVD player and that section that was allegedly defective played PERFECTLY THREE TIMES in a row. “Apology” for not checking for smudge. My humble reason was that the exact seven minutes of video/audio that I had re-wound and played over and over four times was the same section that was damaged. So, I immediately thought it was the re-playing as the “root cause” and not thinking of a simple smudge. My immediate thought was the re-playing caused the problem Curious that the smudge came over the exact same section of the video that I had re-played. I wonder what is the probability of that happening. Again, my “Thank You” for your help.
