What I did is first a cvsps -f stv0299.c to get all patchset numbers and
then a cvsps -f stv0299.c -s <patchset no.> to get a patch file, which
was then applied with patch -R.

This was/is something very confusing for me as a newbie. I did know which
driver to take, there seem to be so many different drivers. But also which
tools to use there is dvbd, dvbtune and szap. Please do see this just
as an observation and not as a complain. I am very thankful for the very
quick replies and help that I get on this list and for all the work done
by the comunity!

It was a soft reboot.

On monday I will have access to the machine, I will then power it off
and report my findings.
