/* set stream output port. Some notes here: The ivtv-derived
encoder documentation says that this command only gets a
single argument. However the Windows driver for the model
29xxx series hardware has been sending 0x01 as a second
argument, while the Windows driver for the model 24xxx
series hardware has been sending 0x02 as a second argument.
Confusing matters further are the observations that 0x01
for that second argument simply won't work on the 24xxx
hardware, while 0x02 will work on the 29xxx - except that
when we use 0x02 then xawtv breaks due to a loss of
synchronization with the mpeg packet headers. While xawtv
should be fixed to let it resync better (I did try to
contact Gerd about this but he has not answered), it has
also been determined that sending 0x00 as this mystery
second argument seems to work on both hardware models AND
xawtv works again. So we're going to send 0x00. */
