Andy, My guess is that this is actually the s5h1409 being dumb in a couple of ways: It puts the same SNR value into both the strength and signal fields. Most demods treat the signal field as a scaled value from 0-65535 where 65535=100%. So femon probably treats 0x012c as 300/65535 which as a percentage is rounded to "0%". So while part of this is femon making some assumptions about how the values are rendered, much of the problem continues to be the lack of uniformity for the strength/snr fields in the DVB interface, and the s5h1409 just happens to do it in an unpopular way. Nick: Just use the non-human readable values. This problem isn't going to be fixed anytime in the near future given the inability of the LinuxTV community to agree on a format for providing SNR/signal info across all demod drivers (I've been pushing for that for *years* now).
