We have recently finished renovations at our house, meaning changes to our existing TV setup.

I want to be able to watch videos from my computer on the TV. The logical solution would be to run RCA cables from my graphics card TV-out and line out on the computer, and into the TV. The problem is that the TV in the room next to the computer room is old and has no RCA inputs! So, to convert RCA to normal RF/aerial cable, I need a RF modulator - I've seen this one which should do the job, but I haven't bought it yet. Basically it takes RCA input and RF input and converts into one RF output. Using this, my problem can be solved like this.
(Also includes input into my TV-tuner card, and involves drilling another hole in the wall!)
This then caused me to think that it would be nice if I could watch videos from my computer on the other two TVs. To avoid running lots more cables, this means I would need to put the computer's signal onto the long cable (dotted line). I had this idea which just connects the output of the modulator to the RF cable. The modulator in then electrically connected to everything else and should output to the other TVs.
My problem is that tihs solution would seem to have things going the wrong way. Everything else is sending signal in one direction (down and left on the diagram), including a booster which makes the signal from the DSTV and DVD/VCR strong enough to get to the other side of the house where the computer and old TV are, and the modulator is sending it in the opposite direction. Is this going to cause any problems in signal strength/quality/anything else? Basically, can I do this and will I be able to see DSTV, SABC, DVDs or VHS tapes and computer videos on all three TVs if I set it up like this?
