Eric,

When you use the scan command to scan for QAM channels, you must
specify -a2, to signify that you are scanning digital cable.

Try that -- does that work?


My bad -- I meant, "-A 2"  (capitol A, space, 2)

scan -A 2 -vvv dvb-apps/util/scan/atsc/us-Cable-Standard-whatever >
channels.conf

Is THAT what you're doing to scan ?


It looks like what you were doing was scan a tuned frequency for pids.
If you want to do THAT, then you must actually be tuned to the given
frequency.  you need to azap SOME_CHANNEL -r, and keep that running
before attempting to run 'scan -c' ... I think you should try the scan
command that I mentioned above.

HTH,

Mike



I was only using one -v, but the scan file isn't the problem.  It is
just the single line out of
/usr/share/doc/dvb-utils/examples/scan/atsc/us-Cable-Standard- center-frequencies-QAM256 corresponding to a known good frequency. Otherwise it scans from 0-70
which are all NTSC and gets annoying on repeated attempts...

Adding two more -v's doesn't change anything, status is always 0x00
and nothing gets written to STDOUT (channels.conf)

~$ scan -A 2 -vvv

The -v is just for verbosity.

My question should have been, "did you give it a chance to scan through
the entire scan file?

-Mike


Yes.

Thanks,
Eric
