[linux-dvb] Problem with SkyStar2 DiSEqC (newbie)

[surabaja at gmail.com]

PCI SkyStar2 + quad LNB on dual feed dish.
I can scan channels on singled-out  LNB output (HotBird or Astra).
However, if I route the two LNB through a 4x1 DiSEqC switch, then:
./scan -l UNIVERSAL -s 2 -x 0 dvb-s/Astra              : works fine
./scan -l UNIVERSAL -s N -x 0 dvb-s/Hotbird           : with N=0,1,3 
returns "tuning failed"....

also, could you please point me to a searchable archive for this list?
Thanks in advance for helping me out.
