This requires Linux DVB 5.5.

Cool hints:
 - If your header doesn't match "Lesser" 3 times, you are not good
 - If you use LGPLv2, you are not good
 - If you use the old FSF address, you are not good

At least the ISDB-T standard export version uses sub-kHz precision
(never mind that one band occupies several megahertz in width).

Multi-frontend adapters (single tuner, multiple standards) provide
multiple frontend nodes and only one demux. So the device number
is only used when selecting the frontend.

I am going to assume that devices with multiple independent tuners
show as multiple adapters (otherwise this is totally screwed).

This needs testing (my DVB driver is not CI-capable).

The missing definitions are 3-days old...

Use cqam:// as BDA already does.

This is done according to oscillator configuration.

This uses the same --dvb-polarization syntax as the BDA plugin, while
also retaining backward compstiblity with --dvb-voltage.

This is the simplest option. Hz resolution is useless for this purpose,
exhibits so many trailing zeroes that the preferences dialog overflows,
and overflows 32-bits values for satellite carrier frequencies.

This is also the default resolution for BDA. I see no need to copy the
"inconsistent" resolution if Linux-DVB (Hz for C/T, kHz for S).

For backward compatibility, frequencies beyond the radar bands are
divided by 1000. This corresponds to EHF and infrared in kHz.

This is untested. Frequency offsets and diseqc are not done yet.

It seems that DMX_ADD_PID does not work. So revert back to the
non-shared DVR node, unless budget mode is enabled.

This is incomplete and hence not automatically compiled. Conditional
Access, DVB-S and scanning are missing. DVB-T and ATSC are not tested.
DVB-C works.

It is not clear to me what the problem is, but it seems VLC does not
like the Linux DVB kernel demux. Only budget mode seems to work
correctly at the moment.
