A recent issue of Amazing (Dec or Jan) had an article on using an
electronic color splitter with Digiview. The splitter used had 
S-VHS inputs as well as composite.

Another question regarding Digiview. When I digitize in hi-res with my 
Microway flickerfixer board installed, I get some horizontal lines of noise
in the upper 1/3 portion of my picture. With the flickerfixer board out,
no noise. Is this a known problem?
