Cannot play mpeg2 movies

[34626]

Jellyfin 10.10.6 in docker on Linux debian 12.9
Im having troubles playing mpeg2 movies on my Android smartphone. I have tried to use external players as VLC and MPV besides the internal and web player, but im told that the media could not be played due to a fatal error.
I use Intel Quick Sync, have tried with VAAPI and Video4Linux, but with same result.
I can play music fine + transcode it and also play h264 movies (bluray rips)
In the logs i get this:
Stream mapping:
  Stream #0:0 (mpeg2_qsv) -> setparams:default
  Stream #0:5 (dvdsub) -> scale:default
  overlay_qsv:default -> Stream #0:0 (h264_qsv)
  Stream #0:1 -> #0:1 (copy)
