I LOVE Archer! It’s one of the best TV shows! I have it so this was an easy one to test on my server (playing back locally) and on my TV (playing back via Kodi using Jellyfin addon and playing back via Jellyfin AndroidTV app. Both connect to Jellyfin server). For fun I installed VLC on AndroidTV to compare.

No difference at all. Not on Manjaro Gnome and not on Fedora. Both with Kodi and VLC installed. Also no difference on my ShieldTV Pro (not comparing TV with my monitors). I disabled its own upscaling to compare.

In Kodi, i use the default configuration besides the Jellyfin addon + audio configured for passthrough + default audio and subtitle language forced to English + subs always on.

I think there is some issue on your side?

Because of you I now watched a whole ep again :)
