The first thing I did after watching the rest of the movie was look at the disc and saw nothing there. It then played fine on my other Oppo 203 without any issues so I didn't bother playing it on the Panny 820. Anyhow, just in case, I did wipe it clean.I have an Oppo 205 and it played just fine. I assume that you checked the surface of the disc? Oppo's UHD players are fidgety when it comes to smudges. Fortunately BU has the discs packaged normally, but I always struggle with sets like the Universal Hitchcock UHDs where there is no way to pull those discs out of the cardboard sleeves without getting fingerprints on them, and it doesn't take much of one to get the Oppos to freeze and lock up. The fact that you can continue as long as you skip that part is why I asked.
