Create a new file ( take an existing one as start point ), follow the naming 
scheme.

a line starting with # is a comment.

S : means sattelite ( T=terrestrial, C=cable )
12551500 : is the frequency in Khz ( lyngsat will give Mhz = 12551 )
V : is the polarity (V for vertival, H for horizontal )
22000000 : symbol rate ( lyngsat will give 22000 )
5/6 : is the fec (forward error code)

You can give several line ( ulimited ) in kaffeine's initial tuning data file, 
e.g.

S 11650 H 27500 5/6
S 12120 V 22000 2/3

Kaffeine will then try to tune to these transponders in turn, to be able to 
read the NIT (Network Information Table) that contains a list of available 
transponders on that sat. Kaffeine will then tune to all these to retrieve 
channels info. The problem is that the NIT differs from one transponder to 
another (and sometimes it's simply not carried ). So on each listed 
transponder Kaffeine will also read the NIT trying to find new ones. So you 
will have to find the right beginning one(s) to get a full channel list. Or 
give all transponders listed on lyngsat's Telstar5 page :)

When done, open Kaffeine dvb config dialog ( CTRL+C ) and choose your new file 
in the list for "Sattelite 1", and click "OK". Now go to the channels dialog 
( C ) and click the "Start scan" button, and wait (it could take some 
minutes :). Have a look at Kaffeine handbook for details.

When you have a good init file ( follow the naming scheme ), send it to 
linux-dvb at linuxtv.org, so it will be added to the database.
