Mike,

I failed to say in the prior note that I had already tried your suggested command.  Here's the result:

paul at Kris-desktop:~/Desktop$ w_scan -A2 -X > channels.conf
w_scan: invalid option -- 'A'

usage: w_scan [options...] 
	-a N	use device /dev/dvb/adapterN/ [default: auto detect]
	-f type	frontend type
		What programs do you want to search for?
		c = cable
		t = terrestrian [default]
	-i N	spectral inversion setting for cable TV
		DVB-T: always off
		DVB-C (0: off, 1: on, 2: auto [default])
	-F	use long filter timeout
	-t N	tuning timeout
		1 = fastest [default]
		2 = medium
		3 = slowest
	-k	generate channels.dvb for kaffeine
	-o N	VDR version / channels.conf format
		2 = VDR-1.2.x (depriciated)
		3 = VDR-1.3.x (depriciated)
		4 = VDR-1.4.x/VDR-1.5.x (default)
	-R N	radio channels
		0 = don't search radio channels
		1 = search radio channels [default]
	-T N	TV channels
		0 = don't search TV channels
		1 = search radio TV [default]
	-O N	Other Services
		0 = don't search other services [default]
		1 = search other services
	-E N	Conditional Access (encrypted channels)
		N=0 gets only Free TV channels
		N=1 search also encrypted channels [default]
	-X	tzap/czap/xine output instead of vdr channels.conf
	-x	generate initial tuning data for (dvb-)scan
	-v 	verbose (repeat for more)
	-q 	quiet   (repeat for less)
paul at Kris-desktop:~/Desktop$
