Hey Jim, I see your name on about 99% of posts, so I have the solution for you, just incase it comes in handy. The problem occurs when you switch outputs on the PS3. My setup is using component into my Roxio Game Capture HD Pro, which is then using a HDMI output into my monitor. Now, when I move the PlayStation to another room to use via HDMI, I will hold the start button to reset its output to HDMI for use on the main television. The next time I bring my PS3 back into the computer room for streaming, I repeat the procedure to reset the PS3s output and set it up to component once again. Now, when I immediately click stream, I get No Signal when clicking on the Live Stream button, dispite the fact that the preview window had my gameplay in it. The solution is to restart your PS3 once you've changed output modes on the console! It's a bit silly, since everything appears to work fine until you click 'Live Stream', but hey ho, that's how I've gotten it to work again!
