Dreambox 500s

I recently just bought a dreambox 500s, because i want to watch cable tv in two different rooms, i have cable tv set up in the living room, but i also want to watch it in my bedroom. i heard that dreambox can help me with this, so i bought a pre-tuned one off ebay, but it was configured for satellite tv, but i have the cable set-up

 

A 500s box is for satellite not cable. The tuner is not pluggable.

 

thanks for answering, i have found an offset satellite dish for a cheap price, how hard would it be for me to set up and also is it possible for me to recieve the pay channels from my living room to my bedroom with this.
