Sold wires on Tobi and tried TV signals out.
Image output is rather  noisy but it works.
Switching is LCD or DVI to TV done by script.

I have already have the  outputs connected to a y/c to composite filter by
Maxium for the best possible conversion. I need to know what the scrips are.
Do you happen to know?

Sure. Its a MAX11503. A demo pcb is available from Digikey. When I get output
I'll post a pic of it. BTW, I figured out the #1 reason for no video is that
a have a console build. Im baking a desktop build now.

Well.... Followed the DSS2 SYSFS Examples guide and was able to turn on the
output, but its hardly NTSC. Im getting a downward ramp of about 100ns
period. Im using a FE with a date code of R3358, which should have the video
output ability.

Any ideas?

The output I got was very noisy but I hope to update with better
news after I get this MAX11503 Evaluation Kit ... any ideas how
to source one ? (AVNET has no stock)

Anyway, i got mine directly from Maxim.
