More: Buffer length in MME

I've just tried uping to three buffers.  It didn't do anything for the lower
limit (in terms of ms) but introduced, as you said, an upper limit.

I can only presume that Rebirth is giving inaccurate info about the MME
latency.  Other than that, maybe my inability to use WAVE_FORMAT_DIRECT has
something to do with it.
