Is it trying to tune in using DVB-S2? The "other" driver was done quite some while ago, and included some clunky code to fallback to S2 if DVB-S tuning failed as it was developed before the DVB API had support for supplying DVB-S2 as a delivery system and this was the only way of supporting S2 back then. This was removed in the in-tree driver as it isn't needed anymore, but this does mean that the tuning program needs to supply the correct delivery system. Have you tried it with dvbv5-scan & dvbv5-zap? Regards, Jemma
