I should note that alwaysBuffer performance may have improved with  
2.7 since a change was made to how QT is handled.  From Whats_New.txt:

"For the QT variant of the player, if QT6 or above is installed it  
utilises
the QTGetTimeUntilNextTask API to ensure that it always updates  
itself when
necessary. This should result in smoother playback than was previously
available - particularly for buffered players."
