It looks like there is a pretty good chance that the Amiga Genlock peripheral
would be able to do this, with a little jury rigging.  One of the things the
genlock will do is to convert the external NTSC video sources into a analog
RGB signal.  You would have to rig up a switch to select the output, perhaps
have to combine the selected RGB signal with composite sync, and have to
have some kind of monitor coming off of the Amiga composite video or tapped
in between the Genlock and the Amiga so that you could effectivly control the
Digiview program.

This is *NOT* a statement that such a configuration will work, just some
discussion about the possibilities.

Also, the elusive Genlock is still scheduled for release sometime around
the end of the year...
