- 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

- 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
