MPF_2.0-net48 doesn't detect protection in DVD-Video discs via Scan for protection feature although the discs are protected and their protections are properly described in the logs when the discs are actually dumped.

http://redump.org/disc/11720/

Taking this disc as an example. Scanning for protection doesn't detect anything.

I think I misunderstood the original request the first time I read it. You're asking for the standalone Scan For Protection to detect the things that DIC outputs. Without a lot of retooling, this is not possible, as those are fully dependent on DIC outputting those values currently. Those are not being handled by BOS as outputs.

I will look into seeing if I can use the DVDAuth.exe executable bundled with DIC to get this output, but I can't guarantee that this is possible.
