SOLVED: Some shows crashing Jellyfish for Tizen

[TheDreadPirate]

It could be.

Is there an easy way I can search to try a different show with the same parameters?

Not that I'm aware of.  I tried to write up some loop and use ffprobe, but I couldn't get all the ffmpeg/ffprobe banner stuff to go away.  The reports plugin doesn't list the frame rate or bit depth.

I don't suppose it's possible from jellyfin to decode and play the file from my server? Or am I going to be better off re-encoding the whole series? 😭

Negative.  The server will decode only when it is transcoding.  You COULD select a really low bit rate in the quality selector to force a transcode as a workaround.
