Function ChooseSegment  is called only once to choose first segment to play.
There is other function, segment_Seek, which is responsible for
seeking in stream.
After thinking it through i guess that it should always be chosen
first segment from playlist (we don't need ChooseSegment function at
all). And if someone for whatever reason need to start closer to
playlist end, then this can be done with start-time option (which
currently doesn't work exactly, but its more like some isse with
segment_Seek function or something like that). What do you think about
