#1 lore raw

Dear Steve,

I am already using the "-F" and the "-t 3" option... So a longer time waiting is not possible.

-F use long filter timeout
-t N tuning timeout
1 = fastest [default]
2 = medium
3 = slowest

And there are "NIT(actual) table" on the frequencies.
My result should be very much like: http://www.dtvmonitor.com/nl/ziggo-noord

But I also search more what my problem could be and I discovered that most examples say:

using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

and i only get:

using '/dev/dvb/adapter0/frontend0'

But I guess demuxing is necessary to get the "NIT(actual) table", isn't it ?

Only is goes already wrong with the init scan.... I only get: "Info: no data from NIT(actual)"

I suspect either their isn't a NIT(actual) table on your frequency, or the tool isn't waiting long enough for the NIT table to arrive.

Generally speaking applications configure the demux to pass all pids, so yes - the demux is typically mandatory. Data is received from the dvr0 device.

Assuming the card is tuning and delivering complete unfiltered transport payload reliably, then if no NIT is appearing then I can only assume either the application isn't waiting long enough, or it doesn't existing on that frequency.
