I am in Asia and I have a Diseqc (should be Compatible with 2.0 version)
which connect with 4 Satellite, LNB1=105.5 LNB2=115.5 LNB3=138.0
LNB4=146.0. And the DVB-S card is Twinhan 1020A.
Everything hardware is working well under Windows system, and
now I want
move it to Linux.VDR has been successfully setup which I can use
it
watching LNB1 channel without any problem. ( I use dvbscan to
scan
generate the channel.conf)
But, when I want add LNB2 or LNB3 and 4's channel, it looks
dvbscan can
not switch to them and tuning. I have spend lots of time Google
the
answer but can not find any useful solutions.
The problem simple description is that the command:
>dvbscan /usr/share/dvb/dvb-s/AsiaSat3S_C-105.5E -l 5750 -s 0
using '/dev/dvb/adapter0/frontend0' and
'/dev/dvb/adapter0/demux0'
initial transponder 4000000 H 26850000 3
>>> tune to: 4000:h:0:26850
DVB-S IF freq is 1750000
>dvbscan /usr/share/dvb/dvb-s/AsiaSat3S_C-105.5E -l 5750 -s 1
scanning /usr/share/dvb/dvb-s/AsiaSat3S_C-105.5Escanning /usr/share/dvb/dvb-s/AsiaSat3S_C-105.5E
using '/dev/dvb/adapter0/frontend0' and
'/dev/dvb/adapter0/demux0'
initial transponder 4000000 H 26850000 3
>>> tune to: 4000:h:1:26850
DVB-S IF freq is 1750000
it looks response the same result(channel list) even if I use
different
"-s N" parameter.
But the command:
>dvbscan /usr/share/dvb/dvb-s/Asia6B_C-115.5E -l 5750 -s 1
scanning /usr/share/dvb/dvb-s/Asia6B_C-115.5E
using '/dev/dvb/adapter0/frontend0' and
'/dev/dvb/adapter0/demux0'
initial transponder 3840000 H 27500000 3
>>> tune to: 3840:h:1:27500
DVB-S IF freq is 1910000
WARNING: >>> tuning failed!!!
If, I un-plug the line from LNB2 and plug into the LNB1 on my
Diseqc,
above command will successful find channel too.
I try to modify the diseqc.conf file, but it looks only worked
for vdr
not for dvbscan...
So, what can I do and any suggestions?

Rocky.Lee
