Hello everybody,
I'm trying to use Deutsche Telekom's "T-DSL via Satellit", an account
which -despite its name- has nothing to do with DSL, but does boost-up
low bandwith connections with a local proxy software by using Astra
DVB-S to have a broadband downstream channel.
(I just mention that to make clear that I really don't want to watch TV,
I just need the network device.)
My setup is kernel 2.4.23, bttv 0.9.12, and dvb-kernel taken fresh from
CVS on sunday. dvbtune is from the Debian package, 0.3+cvs20030922-2
The machine is an older K6 133MHz with 64MB RAM which sits in a closet
serving as the headless router for my home LAN.
Everything went fine so far, the modules are loaded successfully:

When I try to tune the card with dvbtune, I get FE_TIMEDOUT and cannot
lock the frequency:

I've done RTFM thoroughly but didn't find any solution.
The Metzler drivers don't help, their cx24110 module seems to be
outdated.
I didn't find out how to configure the card with szap, if that comes to
someones mind (I dont wanna TV, wanna network).
You can use szap also for non-TV channels too, just set audio and video
PID for your data transponder to 0 or 0x1fff. Since szap is much more
verbose in case of troubles than dvbtune I'd suggest you to use this
tool for debugging - as soon you have a reliable stream you can start to
configure your network connection.
