[linux-dvb] Re: Help needed: No video/audio on Haupp. DVB-C premium2.1 using FC3 kernel 2.6.9 (-681_FC3)

Hi

for me the fastest way to get picture and check whether card
was working okay was to download and build kaxtv.
I am happily using kaxtv 0.23 but there is also 0.30 test available at

   http://hftom.free.fr/kaxtv/kaxtv-0.3test.tar.gz

- If you can czap then you can also try to use tvtime for viewing the 
just zapped picture.
(I do not remember whether you need to use -r switch or not with the tvtime)

- I udev fails to create /dev/dvb and entries under that download newest 
dvb kernel
sources from the cvs and use MAKEDEV-DVB.sh from there to create the 
drivers by hand.

- DVB kernel sources (for getting MAKEDEV-DVB.sh) you can get from the 
cvs by using commands
  cvs -d :pserver:anonymous@linuxtv.org:/cvs/linuxtv login   (press 
just enter for the password)
  cvs -d :pserver:anonymous@linuxtv.org:/cvs/linuxtv co /dvb-kernel

- If you want to test newerst modules from the CVS instead of using 
official kernel dvb modules then you need to do following
  steps. (Not sure whether thet build without problems agains 2.6.9 
kernel but it is easy to try)
   a) build your kernel sources in /usr/src/linux     (needed because 
dvb kernel sources needs some files from there)
         cd /usr/src/linux
         make
         wait...
   b) go to directory where you did get your dvb kernel sources from 
the cvs and there do following commands as a normal user
      cd dvb-kernel/build-2.6
      make
      cd ..
      su
      (enter root password)
      .//MAKEDEV-DVB.sh  (If you have not created /dev/dvb entries 
earlier in this boot and udev rules do also not work)
      cd build-2.6
      ./insmod.sh load

When you find a dvb modules and players up first time correctly then you 
can easily start getting drivers loaded more easily
via scripts...
