Applied [1] + [2] + your path. Unfortunately, this does not work for me. scan-s2 can tune only on the 1st of those 3 transponders on HB13E S1 12654000 H 27500000 3/4 S2 12692000 H 27500000 3/4 35 8PSK S2 11681000 H 27500000 3/4 35 8PSK Please note that I can tune quick/fast on those 3 transponders with a ngene based card. szap will report a signal of 60% and snr of 70% for them. Problem is the CI support does not work for me. I am wondering if there is a dvb-s2 card with ci support which flawlessly works on linux... ? -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
