Here is my hookup (as per Gonk):
1) S-Video from cable box to 1050 S-Video 2 In
2) S-Video from 1050 S-Video Monitor Out to TV
3) S-Video from 1050 S-Video 1 Out to DVD S-Video In
4) S-Video from DVD S-Video Out to 1050 S-Video 1 In

I get no picture from either TV (Video-2) or DVD (Video-1). Sound is fine.

What am I doing wrong???
