Can’t view MPC-HC menu when using MPC-HC as external player

I am having a strange problem with the MPC-HC right-click menu display when using MPC-HC to play MKVs through Kodi.

I rebuilt my HTPC recently and having installed MPC-HC and Kodi before, I haven’t come across this problem (all drivers and OS updates are up to date).

Problem: When playing an MKV in Kodi (via MPC-HC), and I right click, I get a blank screen. Audio still plays, but no picture. I can exit the movie via Alt-x (the MPC-HC command to exit) and it returns me to Kodi, but there is no right click menu via my mouse.

When running the same MKV in MPC-HC standalone, I do have a right-click menu.

This occurs for all my MKV movies.

Build:
• OS is Win 10.
• Video card: AMD Radeon HD 5570
• In MPC-HC, Options, OSD is shown as checked (by default)
• MPC-HC is the latest build, with default values apart from:
o Direct Show video is set for madVR
o Audio render is system default
o Internal filters – video decoder – hardware decoder to use = DXVA2 (copy-back)
o Internal filters – audio decoder – all bistreaming options selected
o Playercorefactory xml doc is located in the folder: C:\Users\USERNAME\AppData\Roaming\Kodi\userdata
• Kodi 4 Launcher (v1.1) has “Focus External Player” checked on the ‘external players’ tab.

Any ideas?

Playercorefactory xml doc …
