some movies i watch start to buffer after about 20 min,
i dont know why for sure but its probably bcus the bitrate is rly high since it only happend to me with movies with bitrate bigger than 60MBPS or so…
i have “Hacksaw Ridge” in 15mbps and 71mbps!, when i started with the bigger one the movie started buffering after 20 min, then i switched to the smaller one and it played smooth, in lower quality ofcurse.
im using LG C1 TV, appletv 4k 2nd gen as streaner and plex as aserver on my computer where i keep al the movies.
my LAN network support 1gb.
