Perhaps I wasn't clear: I don't force scanning to be QPSK only. With just the following one line in dvb-s/Astra-19.2E I was able to scan DVB-S and DVB-S2 (both QPSK and 8PSK) channels in one command with the HVR-4000: S 12551500 V 22000000 5/6 The point is that some drivers and hardware (e.g. HVR-4000) cannot handle QAM_AUTO or FEC_AUTO and will generate errors, but the necessary transponder information *is* available to be parsed and used, so scan-s2 should do that. We need scan-s2 do the best possible scan in one command with the standard initial transponder files for all cards. You can't assume the hardware has AUTO capabilities. Perhaps the capabilities could be checked before the scan though and used if available. Hans -- Release early, release often. GMX Download-Spiele: Preizsturz!
