** Description changed:
The packaging nor man-pages do not make clear that these tools only
support a very old "legacy" tuner format (DVBv3) and as such fail to
work using various instruction sources.
The tuner files are installed via the dependency on 'dtv-scan-tables'
and are predominantly DVBv5 format.
For example, scan will fail with:
$ scan /usr/share/dvb/dvb-t/uk-XXXXXXXXX
- scanning /usr/share/dvb/dvb-t/uk-XXXXXXXXX
- using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
- ERROR: cannot parse'[C49 BBC A]
- '
- ERROR: cannot parse' DELIVERY_SYSTEM = DVBT
- '
- ERROR: cannot parse' FREQUENCY = 698000000
+ scanning /usr/share/dvb/dvb-t/uk-XXXXXXXXX
+ using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
+ ERROR: cannot parse'[C49 BBC A]
+ '
+ ERROR: cannot parse' DELIVERY_SYSTEM = DVBT
+ '
+ ERROR: cannot parse' FREQUENCY = 698000000
'
What is not made clear is that 'dtv-scan-tables' also installs the
'legacy' tables under
/usr/share/dvb/dvb-legacy/
Where the equivalent for the command above would be:
$ scan /usr/share/dvb/dvb-legacy/dvb-t/uk-XXXXXXXXX
However, the tools still fail to parse these files:
