It seems to work fine with DVB-S. But it doesn't work with DVB-S2.
I have took a look at transponders files of reel. And found that files
hasn't any information
about modulation (QPSK, 8PSK)
I don't know how Reel don't use this informations for tuning.
Transponder list does not provide information about modulation. Channelscan does not know about the modulation it simply tries one modulation after another in this order "No modulation Set(for manual scan)/QPSK/8PSK/QPSK_S2". See cScan::ScanDVB_S():scan.c@405.
