MC 4.2.1.2 - not working with MediaInfo.dll 17.10 or newer

In the past it was always possible to grab the latest 32-bit MediaInfo.dll (https://mediaarea.net/en/MediaInfo) and drop it into the MC folder to ensure latest media file formats are correctly read.

I'm finding that the last version that works is 0.7.99.

Subsequent to that is 17.10 and 17.12 and with both of these, when I drop a media file on the MC interface, no media info is extracted. I just get file size. There is no error produced.

As the version number is quite different, I guess they made changes to the API that would then require changes to AMC code for calling it correctly.

Well, they only say "Version scheme is now YY.MM (year dot month, 2 digits each)" in the v17.10 release notes..

..but then the next line is "New MediaInfo XML output, with XSD, more suitable for automatic parsing. Use Option("Inform", "OLDXML") for keeping previous behavior" so if that is the way AMC is interacting with MediaInfo.dll then I guess there needs to be a tweak to revert the behaviour, or a bit more investigation to comply with new syntax.

AMC calls a function of the that returns structured objets, not a text/XML output, so it does not do any XML parsing and it is most likely not concerned by that... except if they completely changed the system in an earlier release (but it does not seem to be mentioned either).
Though that it may be better to use XML for compatibility with future updates.
I'll check that someday maybe, if I've time... but it has been long time since I have done anything in AMC's code (all releases >3.5 were done by soulsnake, who now does not have much time either).
