A:Answer Please check the list of playable media on the following link: https://help.panasonic.ca/viewing/ALL/DP-UB9000P/OI/TQBS0286/TQBS0286.pdf#page=6
It may not be possible to play the above media in some cases due to the type of media, the condition of the recording, the recording method, and how the files were
created.
The producers of the disc can control how discs are played, so you may not always be able to control play as described in this Owner’s Manual.
