Can anyone out there explain to me what the purpose of the Edit Switch is under
the cassette opening on the JVC HR-S5000 tape deck.  JVC breezed over the
feature in their owner's manual (along with everything else, pathetically
written instructions!).

The function of edit switches (in general) is this:

In playback, most VCRs add a certain amount of edge "emphasis" to make the
picture appear subjectively sharper. In S-VHS VCRs, they also "average" chroma
information over several lines to reduce noise. Unfortunately, this causes
chroma displacement vertically, and makes the color appear to be sliding down
the screen.

Turning "on" the edit mode switches out most of the extra emphasis, as well as
reducing the number of "averaged" lines, which helps makes subsequent dubs look
a little better.

Some folks (myself included) find that the machine looks BETTER with the edit
mode engaged all the time. It produces a more technically correct picture in
that mode, though with a slight noise penalty. My best advice is to try
switching it on and off while carefully observing the playback image, and
decide which you like best. It has no function during record.
