I use the CMI VI-500 all the time, works great!

BNC output of what?  The CMI VI has RCA out.

Sounds like you need to adjust your text colors.  When recording RGB graphics
to composite video you have to stay within legal color values.  On an RGB
display you can set the Red, Green, and Blue values from 0 to 15.  But in
composite you can only go to 12.  If r,g, or b is above 12, it will bleed.
And, Red bleeds the worse of all (I guess that kind of makes sense :-).

You might also want to invest in a high quality RCA video cable.  I have a
Signet cable.  It has gold plugs, and had extra shielding.  It's very nice,
and seems to be an improvement over the cheap cables I was using.  I got it
for $30 at a local audio/video store.
