unable to load internal or external subtitles (greyed out entirely)

[doubledgedboard]

MPC-BE 1.6.5 x64 (git 2022.11.11 - 24bf582)
VideoRenderer 0.6.3.1956
Windows 10 21H2

I have an .mkv file which contains internal subtitles that are not being loaded, and the "Load Subtitle" option is greyed out entirely.

I can provide more media information as needed.

It works fine in MPC-HC with madVR, by comparison, or in SubtitleEdit which is also able to extract any of the subtitle tracks, so I know the media file isn't entirely the problem.

Show filters list when play file.
Right mouse -> Filters -> Copy filters list to clipboard.

[Aleksoid1978]

Check - Options -> Subtitles -> Subtitle renderer - set to internal.

[doubledgedboard]

subtitle renderer is already set to internal

filters list:

MPC-BE 1.6.5.0
Filters currently loaded:
  - MPC Audio Renderer
  - MPC Video Renderer
  - Audio Switcher

Must working.
Try reset player & VideoRenderer settings.
Upload sample file.

I can't legally share the file(s) as they are copyright protected.

It's happening with all files from this release from SMURF, but one prime example is The.Crown.S05E03.Mou.Mou.1080p.NF.WEB-DL.DDP5.1.HDR10.H.265-SMURF

If you are able to get that exact file "somehow" then you might be able to reproduce it.

Try reset player & VideoRenderer settings.

[doubledgedboard]

Resetting does allow subtitles to show up, but it doesn't fix the problem as it changes the filter list back to using EVR:

MPC-BE 1.6.5.0
Filters currently loaded:
  - Default DirectSound Device
  - Enhanced Video Renderer (custom presenter)
  - Audio Switcher
  - MPC Video Decoder
  - MPC Audio Decoder
  - MPC Matroska Source

After re-adding "MPC Video Renderer" to the "External Filters" and setting to "Prefer", the problem with subtitles appears again.

[doubledgedboard]

Ah! I got it working.

Instead of using External Filters, I went to the video section and selected "MPC Video Renderer" from there, instead.

Sorry for the trouble. I wasn't expecting the issue to be related to how the filter was added.
