MPC-BE - Can't select a specific video track in one .mkv containing 2.

[PhobosAnomaly]

Hello there,

I'm not sure if it's MPC-BE related or anything, but I do have a .mkv file I just muxed containing two video tracks, two audio tracks and two .srt.

It's a movie with two different cuts.

Audio tracks and subtitles are fine, I can select the one I want to play, the video tracks however, only the first one is available. The option to select track is greyed out.

I can select both tracks using VLC, it's working as intended, but I know VLC is more permissive.

Both tracks plays without problems on their own when not muxed beside that.

I also understand it's not among "best practices" to have multiple video files in .mkv, but the file is solely for personal use, on computer, not on TV or anything, so the option to have the two tracks together is ideal for my use (if possible).


Here's what Mediainfo says about the file :

Is something wrong with it or is MPC-BE unable to handle the track selection for some specific reason ?
