The femon plugin from vdr updates its values every half second. If the driver got only a 
few block errors, maybe you will not see the value.

For DVB-C, it's more interesting to see the accumulated unc value. If you see some 
artefacts, maybe they are a result of the DVB-C transmission or they are a result of the 
DVB-S transmission and the cable provider wasn't able to correct all errors or wasn't able 
to remux the stream correctly. In this case, it is useful to see the accumulated count.
