The interesting thing, is that movies, with the same resolution
(720x576) and same frame rate (50fps) and with Slaughterhouse Five
having audio sample rate 48kHz and bitrate 256kb/s, and Prisoners Of
The Lost Universe having the same data, except with bitrate 160kb/s,
play okay; flowingly, but a movie (and, it is not the only one) such
as The Beguiled, with the same data as Slaughterhouse Five, plays in a
choppy way.
So, in vlc, the Tools -> Codec Details for Streams 0 and 1 (Video and
Audio), do not show a difference that easily shows to me, why the vlc
is unable to play a movie such as The Beguiled, as flowingly as other
movies such as Slaughterhouse Five.
