Just my two (euro) cents: I used to have a saa7146-based older Hauppauge
DVB-T card and with that hardware, my vdr plus the femon plugin did show
reasonable resultsof signal quality. With brand new DVB-T cards with
Conexant  chips, my femon plugin shows only one signal bar (instead
of two) which is always at 100%, even if the device has no lock.

It seems to me that either the hardware or the driver does not report
really usable signal quality data or my vdr (vdr-1.3.20, femon 0.8.1)
does not handle the Conexant cards too well.

I bet the driver is somewhat incomplete, and I really hope that the
hardware is able to produce more usable signal quality data. :-o
Can anyone confirm this?
