Dennis,

I came home and wired it up. Before I plugged the OSD into the video stream, I made sure I had a good picture with the camera etc. Then I plugged in the OSD and no change. So I redid the diagram just to be sure and rewired it....still no numbers etc.
Hmm...I'm suspicious of the connections to the mini pro.
I can't make sense of the your original schematic verses what you emailed me here?
Looks like HSYNC, VSYNC and LOS all need to go to VCC through 1K resistors ....yes?

MAX7456 -> Arduino
CS - > PB2 (10)
SDIN - > PB3 (11)
SDOUT - > PB4 (12)
SCLK - > PB5 (13)

GND - > GND
5 V - > 5 V
Reset - > Vcc
