No second cable needed.

For those who think to lie down a second satellite cable to simultaneously record and be able to look at what I can tell, you can save yourself this work.
The only hacking, you have to stick to the same transponder. This means that in all channels, eg Astra are transmitted works without problems (eg Pro7 record and simultaneously watch RTL). MTV and others are transmitted via other Satellite, there goes not, unless you stay at the same Satellite (transponder).
The do not know many, in my case, I've saved me a lot of work (20m cable, 1/2 day work).

Maybe someone can start something with my recession.
