Hello Michael,

Many thanks for your detailed informations.
I´m using dvb-kernel with 2.4.20 here, and I don´t have any problem
(with one ´full´ DVB-S card.); but friends with 2.4.18 had, so I
tried to find out the reason.

My point was: Let´s fix the dvb-kernel branch, to get more people test
dvb-kernel.
Perhaps, even Klaus might use dvb-kernel one day, if this shouldn´t break
the driver for his many VDR users ;-)

> ...
I´ll attach my logs for 2.4.18 and 2.4.19:
I suppose the needed changes will be trivial for you.
Let´s hope so ;-)
One idea is that Knoppix/Debian isn´t installing the right files
in /usr/include/linux, but I haven´t checked this yet.
