.BI stdio_sync= on|off|number
Set the number of bytes after which to force output to drives with prefix
"stdio:". This forcing keeps the memory from being clogged with lots of
pending data for slow devices. Default "on" is the same as "16m".
Forced output can be disabled by "off".

.BI stream_recording= on|off|number
By setting "on" request that compliance to the desired speed setting is
preferred over management of write errors. With DVD-RAM and BD this can
bring effective write speed near to the nominal write speed of the media.
But it will also disable the automatic use of replacement blocks
if write errors occur. It might as well be disliked or ignored by the drive.
