Dish Network or Direct TV

[KingRanch]

Thanks everyone for the input, I'll try a new reciever and see if that clears it up.
I have a older Oval dish single line(sat110) tripod for those sites covered by trees, and have the InMotion dish on the rig. They didn't wire the external Sat line correctly so I setup a splitter & A/B swith from the cable.
I'm currectly hooked through the Oval and wonder if I should get a new dish & LNB as the inmotion has the switching capability.
Thoughts?
