What steps will reproduce the problem?
1. I have uploaded the sketch to the chip.
2. I connected the Sync to Pin9 with 1KOhm and the Video to Pin7 with 470Ohm.
3. I connected the RCA-Cable (center cable) to 1K and 470Ohm resistors.
4. I connected the Gnd of the board with 75Ohm to the RCA Gnd

What is the expected output? What do you see instead?
The output is the demo text from TVout_R5.91
I can see nothing.

What version of the product are you using? On what operating system?

Please provide any additional information below.
I've checked everything several times. Hardware and software work without 
errors but i can't see anything on the screen.
I have tried all pins

I had the same issue and found that the current wiki shows to use pin 7 for the 
video, but I also did not get any image. On reading a bit more I found that the 
pin used from R5.91 and Beta1 has changed.

I found this in the wiki: http://code.google.com/p/arduino-tvout/wiki/Useage

Here it says pin 8 is used for video, but it will change to pin 7 in the 
future. I changed pins accordingly and it worked.
