Hi there
So repeat this test, but use _another_ run of the same type of cable _outside_ the wall from the video source to your TV. You could perform an A/B comparison between the spliced, in-wall cable to this control cable. (Let's not get in to the validity of A/B testing.)
Wire/cable should be in a conduit. That's a strange story about the cable being not replaceable. Or course the contractor is not going to replace it unless he has to.
Video cables (composite, s-video, component) have to maintain a 75-ohm characteristic impedance. That means you cannot splice it like hookup wire; wire nuts won't do. The only way I would do it would be to connectorize each wire end: one wire with a male connector, the other side with a female connector. BNC connectors would be the best for 75-ohm connections, it's what pro video equipment uses, but are on the expensive side.
Regards
