*Procedure for compiling and loading of drivers*
* unpack kernel-sources (to /usr/src/linux) if necessary
* unpack v4l-dvb-sources (to /usr/src/v4l-dvb)
* unpack szap2-sources (to /usr/src/szap)
* change to /usr/src/szap
* make
* make install => check if szap2 now is installed
* change to /usr/src/v4l-dvb
* v4l-scripts-make_myconfig.pl
* make
* unload all dvb-driver (e.g. make rmmod)
* make install
* modprobe budget
* szap -r ...
* xine
*Problems*
* sometimes the PLL lock after some trys on different DVB-S-channels
* on some DVB-S-channels the Pll never locked
* on DVB-S2-channels the Pll never locked
* some other changes necassary to work with old DVB-programs (like
mythTV)
*Questions*
* Is the tuning with KNC1 DVB-S2 boards also critical? If no then
the main problem must be in STB6100-module.
* It is really able to tune to DVB-S2-channels with KNC1 DVB-S2 board?
* Have anyone the correct entries in channels.conf for Pro7 HD,
Sat.1 HD, ASTRA HD, Anixe HD?
* Do I need any newer tools (like szap)?
Sorry for long text without patch-file.
