I have the Express Vu HD PVR Plus receiver. I would like to connect both tuners in an RV which has only one cable inlet. I have the dish with two LNBs outside. Is there any way to connect both tuners without adding another cable inlet? Somebody suggested using the Dish Pro plus Lnb with a divider. Would this work with Express Vu? Thank you very much for any help or suggestions you can give me.
