That's probably right: it provides the software api to tune a frequency, 
and controls a dsp to demodulate the TV signal, simply placing the whole 
transmitted stream bytes on /dev/dvb/adapter/dvr0.
Fedora's dvb-apps provides tzap used thusly:
tzap -c "a channel" would seem to be actually demuxing the mpeg stream 
to the single program id selected within that tuned frequency. That 
would seem to be needing knowledge of the mpeg data ?
