Great News. I fixed my video. Beleive it or not, it actually came from M$. After several e-mails to M$, I get this procedure:
To reset the display settings of the Xbox 360 console to the default settings, remove any discs from the disc tray. Turn the console off and turn it back on. As the console starts, press and hold the Y button, and then pull the right trigger at the same time. The Xbox Dashboard resets the display settings to the default settings, and then automatically restarts the console. Note If you are using an Xbox 360 Wireless Controller, turn the console on by using the Xbox Guide button on the controller. Make sure that you use the player 1 controller when you do this. The player 1 controller will have the upper-left quadrant light illuminated.
For further assistance, please don't hesitate to write back or call Xbox Phone Support at 1-800-4MYXBOX or 1-800-469-9269 (United States and Canada); or 425-635-7180 (International/direct dial to the US) at your earliest convenience. We are open everyday 9am-1am EST/6am-10pm PST.
After several attempts, It actually worked. Once the box reset, I had my video. I guess I should say thanks M$, and thanks to all you folks that read my post. I hope this can help someone else.
Later...
