combi recorder

I regret this purchase to the extent that I can not seem to make it work for what it is designed, that is to say record what happens on TV.
I receives television by satellite (Atlanticbird3) and decode a Astrell demodulator. The connections have been made correctly (according to instructions) and even trying in other versions without success, the recorder will not record what is the limit for this type of device.
I documented on internet blogs (which I should have done earlier, I agree, it would have avoided an unnecessary purchase me) and it seems that I was not an isolated case but no solution to the problem .
I tried to contact Toshiba not answered me, and Metronic (they answered me) that markets a ditto demodulator has Astrell, but it is still not working.
Do you know this kind of problem and if so, do you know a solution?
GH good day
