It has been posted here that if you hook a color NTSC signal source up to a
digitizer such as DigiView, that you get a rather bizarre fine-detail
crosshatch on color areas due to aliasing of the chroma sub-carrier.

This is indeed true - take it from one who has tried.

Someone just posted an article plaintively asking if there was any solution.
There is (or soon will be).

Both Sunrize Industries and NewTek will be bringing out a device called a "color
separator" which turns color composite video into a Red signal, a Green signal
or a Blue signal. ("or" instead of "and", because it will only do one at a
time, or so I'm lead to believe.)

Just this afternoon I called Sunrize Industries and they said that the power
supplies they've been waiting for are definitely coming on the 26th, and they
will begin shipping against back-orders at that time. The price will be
somewhat less than $100.

NewTek is supposed to ship a somewhat more expensive box around Christmas. The
rumor is that when it is used with DigiView, that it will switch colors
automatically, so you can say "Do it" and it will digitize three times without
further intervention. I'm skeptical about this, myself, because I don't
understand how they'll control it.
