WG: Tuning very unreliable (Technisat Skystar HD2)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello alltogether,


I am in the process of switching my home entertainment system from Windows
to Linux. The distro of choice is OpenSuse 11.2 . Ultimately, I want to run
MythTV with XFCE on it.

My TV cards are two pieces of Technisat Skystar HD2. In Windows, my hardware
works just fine. Yet, in Linux I have problems that I cannot explain to
myself.

I have downloaded the latest s2-liplianin drivers, compiled and installed
them (make && make install). Then I downloaded and installed scan-s2 from
the repository (make). I did this all yesterday night, with cloudy skies and
some rain. While scanning with scan-s2 ?o zap dvb-s/Astra-19.2E I could fine
a number of channels, yet I did not save the channel list. As it was quite
late, I decided to shutdown the PC and continue this morning. However, now I
just get the following response from scan-s2 ? under blue sky and clear
view:

media-pc-wz:~/tv/scan-s2 # ./scan-s2 -o zap dvb-s/Astra-19.2E
API major 5, minor 1

My TV cards are detected (lspci-output):

The only change on my system since yesterday evening, where it worked, was a
?shutdown ?h now?, pressing the power switch this morning and logging in
with my username and password. Nothing else happened.


Mit besten Grüßen / Kind regards,
