BufferThreshold will not affect rate of filling the internal buffer and
so not affect the 404 issue.

"Buffer full threshold" is the level in Kbytes the buffer must reach
before the player starts playing.
Too small and the player will run out of data before next packet arrives
or if there packet flow is lumpy  and so there will be a gap.
Making it bigger just increases the delay between pressing "play" and
hearing music.  

For a slow speed 32kbps stream a setting of 100 would be about 25 secs
delay before audio starts whereas with a 128kbps stream it would be a 6
sec delay and for the BBC DASH Flac  it would be about 2 sec delay.

A setting of 100 for DASH Flac is about 2 sec but each segment is 3.84
sec so it means audio will start when there is only one packet in player
buffer and so for setting less than 100 there is a good chance of a gap
in the audio just after playing starts of next packet doesn't arrive
within about 1sec.

BBC Dash Flac segment (each require a http GET) vary between about
128kbytes and 200kbytes and there is a gap "fetch time"  between each
segment usually less than 300msec but can be bigger and does vary a lot
as noted in the log.

So for higher speed stream it is better to have a bufferThrehsold set as
high as possible.
