[vdr] No Sound and Picture with DVB-S

[Michael Hoffmann <michael@f-j-hoffmann.de>]

I have a DVB-s Card Rev. 2.1.  I tried the siemens 0.94-2002-04-01 driver. 
When I load the driver I got this message:

The PC is a :
Pentium 1 166 MHz
64 MB RAM 
ATX Intel TX Mainboard
Kernel 2.4.17 und 2.4.18

I also tried another PC and it worked, I got a picture of N-TV. This PC is a:
Pentium 2 350 MHz
384 MB Ram
ATX Gigabyte Mainboard mit Intel BX Chipsatz
Kernel 2.4.17

I use the same cable. Has anyone a solution for this problem?
