I've been trying to use HiDive as an immersion source, but because it has separate video formats for the streams of English and Japanese I had to apply a filter in yt-dlp in order to guarantee that I would get the right stream.

That seems to cause issues with migaku-mvp though, since it still gets the audio from the English stream when exporting cards.

I know that MVP overwrites the yt-dlp video format filter with its ytdl-format option so I would guess that for some reason the mpv config isn't being loaded properly. I looked through the ankiexport.py in the migaku-mvp repo, but I'm not sure what would cause that to be happening.
