[Help!] Antenna Settings Twin and Dual LNB's with Dish 21 switches

[srameram]

Looking for antenna settings for my CW600s Regular receiver. The setup is as follows: I have one dish with a twin lnb ie. two cables each providing sats 119 and 110. I have another dish with one dual lnb ie. two cables each providing only sat 61.5. the cables are connected to my two receivers via two dish21 switches(one for each receiver). Does anyone know what my antenna settings should be for my scans? I have tried several combinations but I have been unable to get all my channels. I lose different channels depending on the settings I use. Is it possible that the two dish21 switches are not compatible with my CW600s reciever? If so, what would be a good substitute for the switches in order to get the three sats with the existing lnbs for two receivers or possibly expanding to four receivers? Thanks so much for the help!
