I recently upgraded my phase-II eliptical dish with a SAT-C upgrade and purchased a HD10-250 (HI-DEF tivo). I also needed to install a new 4x8 switch which is cascaded off the existing/original 4x4 switch that is on the back of the dish. When I run through setup on the new HD10 I get no signal from SAT-B. this is apparent too as I can't get all the HD channels. I do get ESPN-HD and CBS-HD. Doesn't seem like i'm missing any other channels. I have the sat-c installed as per instructions to the 4x4 multi-switch and then just took the outputs and plugged them into my 4x8 multi-switch (the instructions on the 4x8 multi-switch - an eagle aspen - said I can plug them anywhere to the inputs). What is my problem? How come I can't see sat-B on my HD10? All other receivers in the house seem to recieve the signals with no problem? Is this the correct way to cascade a 4x8 switch? or should I just remove the 4x4 switch and run all the cables down to the new 4x8?
