Since my 910mp SCART connection went belly up I have been using the GBS8200 interfaced with my GVBVGA Genie v1.0.  The picture was good, but there were a couple of issues that I wanted to see better.  Like when typing the characters did not appear to display correctly on the screen when initially typed but would resolve very quickly.  But enough for me to notice.  There was some video interference on certain colors and could be noticed when colors were solid like a backround of red.
