I've recently started having problems with my picture (breaks up/stops
altogether). In trying to diagnose the problem I see this from vdr
(1.7.15) when starting vdr-sxfe (remote) from xineliboutput (cvs from
4/9/10):

In particular the "lost lock"/"regained lock" looks strange. Searching
through the archives suggests this could be due to a weak signal. I ran
femon and got this:
FE: Conexant CX24116/CX24118 (DVBS)
status SCVYL | signal d840 | snr d800 | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
status SCVYL | signal d8c0 | snr d999 | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
status SCVYL | signal d840 | snr d666 | ber 00000000 | unc 00000000 |
FE_HAS_LOCK

FE_HAS_LOCK
status SCVYL | signal d8c0 | snr db33 | ber 00003e71 | unc 000000a6 |
FE_HAS_LOCK
status SCVYL | signal d8c0 | snr d800 | ber 00000081 | unc 00000000 |
FE_HAS_LOCK
status SCVYL | signal d840 | snr db33 | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
Which looks ok, the snr value seems high enough, so any other reason why
the lock would be lost. I also see this in my dmesg which looks odd:
DVB: adapter 0 frontend 0 frequency 89399000 out of range (950000..2150000)
DVB: adapter 0 frontend 0 frequency 89399000 out of range (950000..2150000)
