is a swm 3 dish compatible with a s4080r dvr

I purchased a used s4080r and it says it has signal on the odd transponders but not all of the even. When it gets to the setup confirmation screen it says cannot detect a signal. The people at direct tv are no help every person i have talked to says something different. I have a d12 receiver in this room right now and it works perfectly so i know its not a connection or signal issue. There are two lines for sat inputs on the dvr so i stole the one out of the next room that had a line going to it but no receiver(we took the receiver for the camper). We have a one by eight multiswitch. A hd dvr in the living room that works fine and another hd reciever that works fine. Any ideas would be helpful because direct tv is of no help. The last person i spoke to actually got an attitude with me and told me there has to b something wrong with my receiver internally and its confusing itself into thinking its getting a signal when its really not. That doesnt make sense to me if it wasnt getting signal it wouldnt get signal and it wouldnt think that it was. If there is something wrong with this dvr its no big deal i only paid $35 for it but i would really love to enjoy the luxury of a dvr in my bed room
