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 runningbefore attempting to run 'scan -c' ... I think you should try the scancommand 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)
