347 argument, while the Windows driver for the model 24xxx
348 series hardware has been sending 0x02 as a second argument.
349 Confusing matters further are the observations that 0x01
350 for that second argument simply won't work on the 24xxx
351 hardware, while 0x02 will work on the 29xxx - except that
352 when we use 0x02 then xawtv breaks due to a loss of
353 synchronization with the mpeg packet headers. While xawtv
354 should be fixed to let it resync better (I did try to
355 contact Gerd about this but he has not answered), it has
356 also been determined that sending 0x00 as this mystery
357 second argument seems to work on both hardware models AND
358 xawtv works again. So we're going to send 0x00. */
