And if that's the case, how does the included kernel module for controlling / receiving mpeg2 transport streams from my DVB card fit with Fedora ?
The hardware manufacturer will have a patent license that allows them
to use mpeg2.  That same patent license most likely does not extend to you
as an end user for use outside of their hardware.


As far as I know there is no mpeg2 decoding done in a dvb driver (it
will probably come from videolinux rather then from the hw-mf.
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 ?
