A Transport Stream is a whole bunch of subchannels multiplexed together. These 
can consist of TV, Radio, EPG and other streams of data or content.

You can either take the whole Transport Stream and save it for later processing, 
use your software (ie Myth) to select which one or more streams are of interest 
to you and save them (multirec), or let the tuner do the selecting for you, in 
which case the filtered stream comes out the .2 port.
