You could use a video sender for about £35 and up. Quality is fair but
no better than a good RF connection. You do get stereo though. Or you
could install network cables and get a specific gadget to use that. I
was also looking at a video unit that uses the mains power cabling the
other day.

None of these are very cheap. I would stick with the coax which should
provide a perfectly good picture.

Can anyone explain why stereo is unachievable through coax? I'm
guessing that if a Sky box is hitched directly to a tv through coax,
that it's mono - my upstairs connection is mono, but I can't recall
how it was done (ie, if there are two coax connecters on the box).
If terrestrial TV can carry a picture, and stereo sound, why doesn't
Sky work the same way?

Just curious more than anything else, although stereo upstairs would
be nice!

Thanks

Because Sky isn't terrestrial TV. So it doesn't use the same systems. i.e. it
doesn't use NICAM to multiplex the stereo sound along with the picture.
For the Sky box to output a NICAM signal over co-ax, so you could decode it with
your normal NICAM TV, the Skybox would need a NICAM encoder, which would make it
expensive (because the consumer market is only in decoders, not encoders -
that's done at the broadcast end).
