These were discovered through w_scan application.

I've read on some page from linuxtv wiki that most of transponders files
needed to be added a 167k offset to work.
Honnestly, it works fine with or without this offset for me.

I do receive both French and German channels.
So obviously, some come from Nordheim antenna while others
are likely to come from Germany but I don't know how to differenciate these.

I have some table frequency list here:
http://www.tvnt.net/V2/pages/342/medias/pro-bo-doc-tk-frequences_tnt.pdf

See the "Canal" array, page 20 for "Strasbourg".
I don't know how to determine transponders frequencies from this list.
