I bought the Pinnacle Studio Moviebox Plus last year to record some gameplay footage from my Xbox 360 so I could make movies. However, my PC at the time was not powerful enough to run the start up software. I recently obtained a laptop capable of running the software, and decided to try recording again. However, I cannot figure out how to set up the capture device (a Pinnacle 510 USB) with the Xbox to record. I tried directly inserting the Audio/Visual jacks from the Xbox into the capture device, and after an initial try, which only resulted in a green screen which recorded sound but no footage, every time I inserted the jacks, it told me that a "valid input signal," could not be detected, and that I should check the cables. I have, and they seem securely inserted. Is there something else I have to do? Or do I need to change some settings? I would appreciate any help that couold rectify this issue.
