Usually used together with DMX_OUT_DECODER, but the AV7110 driver
will always direct the output to the MPEG decoder, too, to keep the
hardware busy, and to let you watch while recording. The API is
not totally clear here; maybe dmx_output_t should be a bit set.

DMX_PES_TELETEXT means "do VBI insertion".
DMX_PES_SUBTITLE is unclear because there's no hardware that
can automatically take care of DVB subtitle rendering. For current
drivers it does nothing.
