OK, it seems he did a backfeed. We can do this. But it would be simpler to go direct, if your wiring supports.
I am going to make some assumptions. Correct me where I am wrong. I believe you said all your TVs are "analog" which I take to mean SD. But I don't know why you would have a ViP222K receiver if all your TVs are SD. And there are only 5 locations you are really interested in feeding. I assume your primary TV is connected by coax to the "CH 3-4 TV1 output" - left click on the below to make it bigger and you can see.
Next to that is a "Channel 21-69" output. To this, you can connect a coax which is in turn run to the input of your 8 way splitter. Then, from each output of that splitter, you have a coax run straight to various TVs. You will have to do some menu work to establish channels, but we can go over that later. If this works, each of the TVs fed from the splitter will have two channels to choose from. You simply use the TV tuner as if it were an OTA signal. Perhaps channel 25 & 60, for example. If this does NOT work, you can get a
4 way distribution amp, similar to what was posted above, but cheaper. Put it in place of the 8 way splitter and plug it in. If you really want to feed more than 4 remote TVs, then move to the 8 way distro amp.
If your primary TV is in fact an HDTV, then it is likely connected to the HDMI/HDTV output rather than the "CH 3-4 TV1 output." All else remains the same, assuming SDTVs elsewhere.
It is possible your main TV, especially if it is an SDTV, is connected to the composite or S-Video outputs. Point is, we need not fool with how this primary TV is connected, assuming it is working. You need only use the Home Distribution option for the other TVs.
Is this making any sense? We can discuss building upon the back feed setup, but that is just a tad more complicated. A lot depends upon how easily you can get to these components and coax.
