This may habe different reasons:
- The drive does not read the medium (DVD+R/RW has not the best
quality for exchanging between different drives).
- The OS driver tries to mount the medium from a wrong start sector #
- The OS filesystem does not support the right UDF version for
real time video.

If you just fixate the medium, it is unlikely that you get any advantage.

The disk has one track that has been finished with a short lead out.
There is a second track that is currently been written to.
I cannot tell anything about the file system data structure inside
readcd f=/dev/null sectors=0-15872
readcd f=/dev/null sectors=15888-1225952
should both give no errors on your system.
If you verify this, then the problem is the filesystem on the medium....
