I have loaded many recivers with files but never been asked to I.F out to loop a legit receiver. When I hookrd up this new SV 4000 today the person wanted their real reciever (5900)to stay working as well so I looped it from the I.F out coming from the sonicview and it worked. After loading a bin to the SV the real reciver no longer gets a signal from the I.F out. Ant solutions using this or will I have to use a sw switch and will the bell receiver pick up a signal thru one of these switches since I can't tell it what port to pull from?
