I'd like to be able to record the s/pdif output of my DTTV receiver onto
CD-R. However this means either moving the CD-R recorder (which is awkward
for other reasons) or running a long co-ax from room to room.

I have a long run of co-ax so that is probably what I'd do for
test/comparison purposes. But if I can I'd like to be able to 'split' the
s/pdif signal so I can use in both places. This means finding a box that
will provide two s/pdif output streams from one. (Presumably, a box which
will need an amplifier, so has to be powered.) I may also want to put an
isolating transformer in the room-to-room s/pdif link to avoid any risk of
ground loops.

Anyone know if a splitter of the kind I'd need is available, if so, where
from, and at what cost? :-)

As SPDIF has similar electrical characteristics to video a video DA
will work. I've used a Keene KDA video & audio DA (currently £70) for
this very purpose and it works fine. I removed the HPF on the s-video
branch to give me 2 video DAs.

If your SPDIF source has a healthy output level, and your receivers
are sensitive, you might get away with a passive splitter.
