According to logs, everything seems to be fine. You could not compare
statistics numbers between two drivers. SNR 0096 is 150DEC, which means
15dB, IIRC it was max chip could return for DVB-S.
No idea about sync etc. problems, are you sure about those? I am pretty
sure it works rather well as I haven't got bug reports from PCTV 461e
users which has that same demod + tuner.

Hello Antti,
the guys from tech@xxxxxxxxxx told me to contact you because of my
problems with the drivers for my DVBSKY S952.
I attached the whole conversation. Currently the main problem is if i
use the current drivers via
git(http://git.linuxtv.org/cgit.cgi/media_build.git/about/) my single
TT-Budget card works fine. But the signal from the DVDBSky S952 is very
worse: Sync problems, bad SNR, drops on video and audio... If I use the
driver dvbsky.net provides (media_build-bst-14-141106), the signal on
booth tuners is fine - but then my TT-Budget doesn't works anymore (see
end of this mail aka starting the conversation with tech@xxxxxxxxxx).
Do you have any ideas, how I could fix this problem? Before I updated my
system (from Debian Wheezy with Kernel 3.2.0-4-amd64 everything was fine
with both cards.
If you need more detailed information, please let me know, so I could
provide them as soon as possible,
Thanks a lot and best wishes
Chris

Hello,
Could you report this problem to Antti Palosaari crope@xxxxxx
<mailto:crope@xxxxxx> and cc to linux-media@xxxxxxxxxxxxxxx ?
Antti is the author/maintainer of M88DS3103 driver.
Please list the compare result of the driver from DVBSky site and
Linuxtv.org.
Max from DVBSky also register linux-media mail list.
He will get your report and co-work with Antti to fix this issue of
M88DS3103 driver from Linuxtv.org.

Hello,
with the drivers from linuxtv.org and the firmware provided by your
site, both cards work.
But the DVBSky card (Montage M88DS3103) do now have a really bad
SNR!TT-Budget C-1501 works as expected. See the output of femon - the
signal of the DVBSky card was excellent with the drivers from you
site... Any idea, what could cause the problem? TV signal provided by
the DVBSky sometimes drops :-(

Hi,
I reinstalled after updating my system with the Linux drivers for the
dvbsky cards provided by your site (media_build-bst-14-141106).
Compiling with the build_x64.sh script was successfully and I could
install the needed drivers via make install. After that the Conexant
Systems CX23885 (DVBSKY S952) card works perfectly.
Unfortunately after installing the drivers my Philips Semiconductors
SAA7146 (TT-Budget C-1501) card doesn't runs anymore - the card worked
perfectly before installing the provided drivers from your page!
If got following error message in the kernel-log:

I think something went wrong with the provided driver packes or some
drivers where overwritten, and some necessary not... I couldn't found
any solution in the internet.

Could you provide me any help for a solution getting the SAA7146
(TT-Budget C-1501) card working again with the kernel 3.16.0-4? With
the kernel 3.2.0-4-amd64 (with Debian wheezy) and the drivers
media_build-bst-13-140526 I didn't had the problems... everything
worked fine. Downgrading is no solution :-)
Attached the complete dmesg protocol.
Thanks a lot!
