Yep, having the buffer watermarks configurable is useful, so apps which
are not latency sensitive can work with larger buffers and sleep longer.

Its also nice for applications to have some filedescriptor they can
sleep on, so they can wait for multiple events using select() or poll()
btw.

For HDTV it doesn't, yes.  I have a snippet hdtv material on my disk,
my machine can't playback that in realtime without framedrops ...
