perhaps it's the backend of those phonon-backends that makes the differences?
or it could be the way the players work. threaded vs non-threaded and taking
into account dropping frames due to slower processing or whatnot.
it's too bad phonon-xine isn't that much supported, because i think it's
great.
in any case, i would try to find out if vlc uses a native pulseaudio, or if
xine does...
there could be an equalizer or automatic sound-volume adjuster, or whatnot....
