Just got a VIP 222 HD receiver. Live in a condo development and share satellite feeds, two dishes (1 is 119 and the other 110). They go into a DP34 switch at the end of our block. The input into my condo is just one feed coming out of the DP34 having both signals for 119 and 110 on it. The VIP 222 has two satellite inputs and my local installer reckons I need two input feeds to use both tuners. He reckons if I upgrade the switch to a DP33 then I can run both from one feed ? This is where I'm confused. If there are two satellite ins on the receiver even if I have one feed will both tuners work ? If not can I not just split the feed coming in into the apartment with a bog standard splitter instead of a new switch ? If I do need a DP33 does it matter that the input is coming out of a DP34 before it gets to my apartment ? Any help much appreciated as I'm not a techy.
