Another issue I've noticed just now: The UCBLOCKS measure isn't reset:
it seems to be an accumulative counter, which isn't correct from the
DVB API (if I remember correctly).
This explains why tvheadend's "quallity" measure gradually tends to 0,
since it is assuming UCBLOCKS is non-accumulative.
2.2.7 FE READ UNCORRECTED BLOCKS DESCRIPTION
This ioctl call returns the number of uncorrected blocks detected by the
device driver during its lifetime. For meaningful measurements, the
incrementin block count during a specific time interval should be
calculated. For this command, read-only access to the device is sufficient.
Note that the counter will wrap to zero after its maximum count has been
reached.
