Hello!
Have some problem with playback large 4k movies on Jellyfin Client for Android TV. It cant open big file - give error. Tryin native players, and additional (VIMU media player) - same result.
If I open this file via SMB in VIMU - it works well. On mobile android version Jellyfin client it works well too (via HTML web player). But if i open it in Jellyfin TV via VIMU - it doesnt work.

How Jellyfin TV client works? It have some "buffer zone" or something else? Can I open files in VIMU directly from Jellyfin TV, without this "buffer" ?
Sorry for my bad english
