was going to hook up two tv to my 360 but have no real cable out to tv just the red yellow and white wires.but now are just trying to find out what the'if out'cable connection on the back of the 360 is for. if a nother reciver is connect to it would it work to .
Yes, if you have another receiver you can connect it to the IF OUT on the 360.
Keep in mind that the second receiver will only be able to view channels on the same sat and transponder as the first receiver (plus a couple other transponders on the same sat)
If the first receiver is off then all sats will be available for the second receiver.
