Open ground in your CATV system... Very very common. You are probably seeing the signal from your cable box/VCR/DVD, plus a weak piggyback of a local TV station. This causes your exact symptom when you say it's the same on more than one TV.
Is your Cable Box, VCR or DVD set to output on a channel that is a receivable TV channel? BINGO That will cause your line. If both Ch 3 & 4 are channels with local signal being broacast, only relief would be to convert the 300 ohm flat wire that is inside each TV between the ant terminals and the tuner, over to shielded cable. Or you could try wrapping the wire with foil and grounding it, but that might also cause other ghost problems.
