  I have not used much czap, I have done testing with dvbtune, and then
went to VDR http://www.cadsoft.de/people/kls/vdr/ . Is your plan to run
VDR also?  Just test it straight away, might work out of the box.  Or you
can use the perl script below to convert from vdr to czap channels.conf:

#!/usr/bin/perl -w
use strict;
while (<>) {
    my ($name, $freq, $opt, $dev, $sym, $vpid, $apid) = split /[:,]/;
    next unless defined $apid;
    my ($inv, $fec, $qam) = ('INVERSION_AUTO', 'FEC_NONE', 'QAM_64');
    if ($opt =~ /M([0-9]+)/) {
	$qam = "QAM_$1";
    }
    if ($opt =~ /I0/) {
	$inv = 'INVERSION_OFF';
    }
    if ($opt =~ /I1/) {
	$inv = 'INVERSION_ON';
    }
    $freq *= 1000;
    $sym *= 1000;
    print "$name:$freq:$inv:$sym:$fec:$qam:$vpid:$apid\n";
}
