Hi folks, newbie here. I'm in an RV, using a Kingdome 9702. Dish says I need to be on sat. 129 to get locals in HD. I have a good signal strength, did a check switch and a reboot, but the check switch says input #1 OK on sat. 129, but just XX on input #2 and Switch SWAJ. I can't record one program and watch another and some channels won't record at all. Like I said, newbie here. Oh and the receiver is the Vip722k. Thanks in advance for any help!
