------------------------------------
If a signal splitter is out of the question for the reason
of maintaining signal integrity, then a rather reasonable choice
would be to obtain a "proc amp" (Processing, I guess) or a video DA
(distribution amplifier). A proc amp gives you control over
luminance, chroma level, & hue, and might provide several video
outputs. A video DA has no processing controls and might provide
from 4 to 10 outputs. It is also common to have an audio DA
combined with a video DA in the same box. These are available from
industrial video suppliers. I don't have any of my catalogs with
me at the moment, but if you have an 800 number directory, there
are quite a few such suppliers listed in there. Seems to me I did
a bunch of business with CVEC Industrial Video out of Chicago a few
years back. (I could be wrong about the name, but the 800 number
assistance operator is still free, I hope.)
And now for the quick & dirty section. Radio Shack has
some sort of a fix for most situations like this. However, the
video signal you obtain may not be as pristine as necessary. I
don't know for sure, but they very likely have some sort of line
signal amplifier that could at least provide you with enough signal
level for splitting. Or, you might be able to grab the RF output
of your VCR and run it through one of their processors to convert
it to a composite signal.
Hope this helps.

Don't forget the PCM tracks on Hi8 - best audio I've found in an industrial
format...

Also means you need a video signal input at the same time. Generally not a
problem, but it also means you can't edit or record without that...and you
can't really effectively edit _to_ it without video. Hi8 PCM tracks are not in
the video track, so that's not a problem.
Oh well, every tech-trick has an upside and a downside...
