I Need Help!

[Slim 7E]

I have a new HD setup in my room, so i changed my xbox's output to HD, have all the cords and colors hooked up correctly, I changed the Roxio input to 480P/576P/720P/1080i and I've tried 480P 720P and 1080i display on my Xbox's HD settings and I'm still having this problem

 

while I'm playing a game my tv goes black and says no signal then 3-10 sec later the picture comes back, and while there is no signal on my tv I can still see the gameplay on my Roxio Capture

 

Please help, I need advice
