Thanks for the many replies !! To clarify some of my errors and
I did mean that he has the older 3 wire component audio/ video, with
The attic space/ head room is most limited, from the current Cable box
closet area, to the hanging TV. The ceiling has insulation batts
running across the top of the joists. There is no physical support, to
crawl on top of the joists. I assume the original owner made that 3
wire component run, before the ceiling was finished.
His remote controller must be microwave (v optical). He can command
the cable box, through the dry wall side of the closet, from the TV
viewing room. While not optimum, it works.
I would be concerned about the suggested options, of pulling a HDMI
(or coax) cable, by utilizing the existing wires. If he fails, where
he is unable to complete the new HDMI run, then he will use of the TV.
I was under the impression, that an HDMI cable input would provide a
superior TV picture/ performance, vs the current 3 wire?
Perhaps we should be sure we have the terms right.
Composite ia a single video coax and 2 audio signals (3 RCA jacks)
Component is 3 video coaxes (RGB) and 2 wires for audio (5 RCA jacks)
You will only get NTSC quality signals out of a composite video that
has not really improved since color TV came out in the 50s
Component video will give you HD if that is what the signal is. You
probably will not see much difference either way with an SD broadcast.

As long as there is room to be able to crawl, doesn't sound so bad
to me. For a limited operation like that you can just support
yourself joist to joist. Or get a length of plywood, lay it across.
The insulation on top makes it a little more difficult, I'm assuming
that is extra that was added on top. If so, you can probably just roll
it back, do the work, put it back. You already have the holes drilled
for the existing cables. Should be pretty straightforward.

I made up some 1x12s with cleats that lock into the truss chords. (26"
long with the cleats at 22.5"). Those are easy to move around in areas
that do not have nailed in flooring and you can slide one out in front
of you, pull the trailing one behind if you are in a very low part of
the attic. We have 2:12s and 3:12s here that are only 4 or 5' high at
