lamedb

Hi guys,

I have a question regarding the structure of lamedb file.
It looks like it consists of 2 sections:
- transponders
- services

Transponder section looks like that:

001f0000:0001:002a
	s 12640000:15000000:1:3:31:2:0:1:2:0:2
/

Service section looks like that:

d048:011a0000:090a:0002:1:0
True Movies 1
p:BSkyB

My question is how does the service "know" which transponder it is for?
