as good as 3 coax, no?
Not if you are using baulins. If you are using a transceiver system than, yes, CAT-5 can carry a signal as well as high level coax. Baulins do not include the necessary compensation networks for the signal losses. Indeed, different brands of CAT-5 will have losses at different frequencies and at different levels. In some cases, the manufacturer mandates that you enter the brand of wire used, in others (Extron) it sends a signal down the brown pair to determine the appropriate level adjustments and in others (Crestron) you need to make these adjustments manually, per run/per transceiver using test patterns. All a baulin will do is correct the impedance mismatch so that a 110 ohm wire can be connected to a 75 ohm device without the impedance being an issue that affects video quality.
Not that anyone cares but I'm with those who are mystified as to why you used a high quality display when you decided to send it such a low quality signal. I understand your rational but if modulation was the road to simplification then might it not have been better to use a lower resolution screen that would hide some of the warts in that low level signal? I, too, think it's a macrovision issue. I have seen it on DVDs as well as VCRs. You might have tried a video stablizer to strip off the macrovision before modulating but.......
