Ok. I'll then close this BZ, as there's nothing we can do to fix a
driver-specific issue on Kaffeine.

One thing you could do on Kaffeine, though, is to increase the timeout at the
device's config. Giving more time for the algorithm to lock sometimes solve
issues with low C/N.

HI,
In fact the problem diden't comes from Kaffeine but from STB0899 driver.
The driver won't lock with low c/n ( the driver from technotrend / windows
does on the same machine)
I have made a setup with vlc and correct syntax -> same problem.
I've loaded the driver in verbose mode to analyse this ...

I 'll try to contact the writer of the driver  Manu Abraham via gmail

Could you provide mode details? What's that "special satellite"? What versions
of libdvbv5 and Kaffeine you're using? Please enable Kaffeine debug logs and
attach.

Hello, I've made the test. The changes in libdvbv5 did not solve the problem of
the DiSEqC commands.
In one search for a special satellite the address of lnb must not change, but
it does! The address is changing over all four positions f8, f9, fa and fb.

Thank you for your support!

There were some bugs at libdvbv5 with regards to support for multi-LO LNBf
devices like the Universal type. It was fixed this Monday.

Could you please test again, compiling v4l-utils from its source? You can get
its source from its master repository with:

   git clone git://linuxtv.org/v4l-utils.git

and build/install it with:

   ./bootstrap.sh && configure && make && sudo make install

I have made a test with v4-utils-1.12.2 (libdvbv5) and kaffeine-2.0.5-1.
The scan seems to be scanning across all LNB's (four), searching for the same
transponder which is defined in 'scanfile.dvb', regardless the satellite name.

good news,
but unfortunately I'm not able to deal with upstream...
so I can't test.
Can somebody do it?

I applied some patches today meant to fix Kaffeine. Unfortunately, there's a
bug also at libdvbv5. So, you need to update libdvbv5 too, from upstream, in
order to be able to test it.

I double-checked the logic: Kaffeine doesn't check if the signal
is too weak for DVB-S/S2. I suspect that this bug is, instead,
related to a DiSEqC bug, as I got a report that Kaffeine is not
sending the right command to the DiSEqC switch. I'll need to
investigate it further. Unfortunately, right now, I don't have
any environment to test DiSEqC.

Same here with lowest C/N and V2.05
was ok with v1.22, perhaps AGC problem ?

I agree that #366302 is not fixed yet. On 2.0.5 I get the following log, when
starting to scan for channels:
