I have a 3 LNB dish that only has 2 cables coming out of it hooked up to a "Petra M01-3401P 3 x 4 Multiswitch" (can't link directly to it since I'm a new member; search for it on buy dot com). From that multiswitch I have 2 cables going to a HD Tivo and 1 cable going to a standard receiver. The standard receiver can only see odd transponders while the HD Tivo has no problems. I tried switching the cables and the ports they're connected to with no luck. If I hook the standard receiver up directly to the dish, it works fine. I assume the problem is the multiswitch, as it was very cheap ($12.99). I'm going to purchase another multiswitch, but want to make sure I'm buying the right one. I only need a 2x4 multiswitch since I only have 2 cables coming out of the 3 LNB dish, correct? If I can only find a 3x8 or 4x8 multiswitch, will it work with just my 2 cables coming from the dish? Thank you in advance for your assistance!
