I tried to use w_scan for creating the initial tuning data for other
scanning utilities. Finally I created them by hand and succesfully used
dvbv5-scan, which found almost hundred channels. Here are the details of
a sample channel:

[TVP 1]
	SERVICE_ID = 101
	VIDEO_PID = 101
	AUDIO_PID = 102 108
	PID_06 = 106
	PID_05 = 152
	FREQUENCY = 546000000
	MODULATION = QAM/256
	INVERSION = AUTO
	SYMBOL_RATE = 6900000
	INNER_FEC = NONE
	DELIVERY_SYSTEM = DVBC/ANNEX_A


I tried in particular the following parameters:

w_scan -fc -c PL -x

w_scan -v -fc -c PL -t 3 -x

w_scan -vv -fc -c PL -i 0 -t 3 -x

w_scan -vvv -fc -c PL -i 1 -t 3 -x

w_scan -vvv -fc -c PL -Q 1 -S 0 -i 1 -t 3 -x

Here are the excerpts from the output of the last call:
