/* My Blu-ray burner LG GGW-H20 writes junk if stream recording is combined
with buffer size 32 kB. So stream recording is allowed only with size 64k.
This makes it worth to have a special case for GNU/Linux buffer size here.
Older BSD info says that 32 kB is maximum. But 64 kB seems to work well
on 8-STABLE. It is by default only used with BD in streaming mode.
So older systems should still be quite safe with this buffer max size.
