[vdr] details on installing siemens DVB driver?

[Stefaan Coddé <Stefaan.Codde@pandora.be>]

I'm new to linux and trying to install the siemens_dvb-0.9.4-2002-04-01.tgz on suse 7.3
cd /usr/local/src
tar -xzvf /cdrom/siemens_dvb-0.9.4-2002-04-01.tgz 

Then i'm stuck

It decompresses to a directory called siemens_dvb-0.9.4-2002-04-01
I found some info on the net to switch to /dvb/driver afterwards but that directory
is not created. A driver dir can be found under the siemens_dvb-0.9.4-2002-04-01 directory
but make can't run 

How to get the driver indeed under a /dvb/driver directory and to reach a correct make?
