I didn't check the diff files yet, will do it when I get home.
But I don't think QPSK should be used by default. I have a version already
where you can specify which scan mode you want to be performed DVB-S or
DVB-S2 by specifying S1 or S2 in freq file, also if you implicitly specify
QPSK in frequency file the utility will not scan DVB-S2, same logic also for
8PSK that will scan only DVB-S2 and will not try to scan DVB-S.
I'll push that version soon to the repository.

The default should stay the AUTO mode since there are cards that can handle
that and their owners might have simplified frequency file version.
