I hadn't stopped to think about the word "video". Have I understood the
links correctly in thinking that squirting the (analogue) video o/p from my
VCR to a tv via Cat5E is not really feasible?

It's feasible technically, but the price of the necessary kit is
(well) over the top. There's nothing deeply, inherently exotic
about the kit, it's little more than a couple of well-built specialist
miniature transformers. But they're made in small quantities and used
only in "professional"/commerical/industrial situations (where there
happens to be a ton of Cat5e already installed) that it's much more
cost-effective, for domestic video distribution, to put in a couple of
lengths of decent-quality coax, which domestic kit is all set up
to feed. If you already have the Cat5e in place, can't face recabling,
and fancy a go - by all means spend the money...

Hope that helps - Stefek
