The extra information is ok. I could write a program that just parses
the relevant information for the libdvb and ignores the rest. We may
need something for the LNB information, though. I don't want to use
any extra libraries, because I want to keep libdvb simple. 

There is an example for a conversion program that uses the lyngsat
tables for the Nokia receivers and turns them into .dvbrc. My first
step would be to write something like that and keep both formats for a
while and then phase out the old one and switch to XML.
