[linux-dvb] scan not working on hotbird/sirius?

[Josef Wolf]

Hello,

I have some troubles to scan the satellites for available channels.
I have 3 LNB's connected via a diseqc switch The positions are:

 diseqc-pos 0: astra-e19.2
 diseqc-pos 1: hotbird-e13.0
 diseqc-pos 2: sirius-e5.0

I have installed ubuntu-gutsy with two TT-budget cards.  Then I do:

  # cd /usr/share/doc/dvb-utils/examples/scan/dvb-s
  # scanopts="-U -p -e3 -o vdr"
  # scan -s0 $scanopts Astra-19.2E    >~/astra.out
  # scan -s1 $scanopts Hotbird-13.0E  >~/hotbird.out
  # scan -s2 $scanopts Sirius-5.0E    >~/sirius.out

For astra, this seems to work as expected and finds 1138 channels.

But for hotbird, only transponders explicitly mentioned in the
initial-tuning-data-file are actually scanned.  If I add more
transponders (data found from lyngsat)to the initial-tuning file,
more channels are found.

This is what I get for hotbird:

  # scan -s1 $scanopts Hotbird-13.0E >hotbird.scan

  Done.

So it looks like scan don't really recognize the satellite, since it
tries to tune to S0.0W.  But nevertheless, I have given -s1, so scan
should know that it should use diseqc position 1.

Any ideas what's up here?
