Roger: You are asking questions regarding the internal format of the 
byte stream coming from the transmitter.  The driver doesn't do anything 
with those bytes beyond just passing them all verbatim to the 
application.

My previous brief response is that this issue has really nothing to do 
with the driver.  You should be asking these questions on a more generic 
DVB mailing list / IRC channel.
