Scanning an unknown satellite without knowing at least the
transponders can take a long time and hang the ARM on occasion.
I got the list I posted for the W3, by writing a File like:

LNB ID 0 TYPE 1  LOF1 9750000 LOF2 10600000 SLOF 11700000 DISEQCNR 2
  SAT ID 7 NAME "W3" LNBID 0 FMIN 10700000 FMAX 12700000
    TRANSPONDER ID 0001 SATID 0007 TYPE 0 FREQ 11175000 POL V SRATE 27500000 FEC 3/4
    TRANSPONDER ID 0002 SATID 0007 TYPE 0 FREQ 11283000 POL V SRATE 27500000 FEC 3/4
    TRANSPONDER ID 0003 SATID 0007 TYPE 0 FREQ 11324000 POL V SRATE 27500000 FEC 1/2
    TRANSPONDER ID 0004 SATID 0007 TYPE 0 FREQ 11492000 POL V SRATE 30000000 FEC 3/4
    TRANSPONDER ID 0005 SATID 0007 TYPE 0 FREQ 11534000 POL V SRATE 30000000 FEC 3/4

which I got from the PDF you posted and than I wrote a little program
using the libdvb (found on http://www.metzlerbros.org/dvb).

#include <iostream.h>
#include "DVB.hh"

int main(int argc, char **argv)
{
        ifstream con(argv[1]);  
        DVB dvbd(0);

        con >> dvbd;

        for (int j=0; j<dvbd.num[TRANS]; j++) {

                dvbd.SetTP(dvbd.tps[j].id,dvbd.tps[j].satid);
                int l = dvbd.search_in_TP(dvbd.tps[j].id,dvbd.tps[j].satid);

        }
        cout << dvbd;
}

It used to be much easier when you could still get the sat lists for
the nokia receivers from lyngsat.com. In that case n/r/tuxzap could
read that list directly. The programs should also be able to read the
xml format of dvbtune.
