Thanks, Elroy. I finally got it to load and play. Initially, on my first go-round, I cleaned the bottom side first. No go. Then I cleaned the top also, per another QQ'rs suggestion. Then it loaded and played. However, the DTS MA side started dropping out on track 2. So I went back to the menu and tried the Dubbly TRUE HD side, and that worked, without a hitch (so, everyone, what audible difference would one hear between the DTS MA and the TRUE HD? Anyone?). Hmph. I also was in contact throughout the day with OPPO Support, e-messaging back and forth. Gotta give props to OPPO for being available on a SUNDAY!!! Quite surprising, I must say. I'm not giving up on playing the DTS MA. Baby steps. Thanks everybody!
