Hi. I recently bought a Hauppauge HD PVR to record my gameplay and planned on using it with my Mac and EyeTV. I bought EyeTV DDT. So when I have all audio and video cables plugged in to the TV,PVR and console, I then go to plug in the USB while I have eye TV open. And I plug the USB in, the TV screen goes black and displays the "No signal" error 3 seconds later! It is really annoying as I can have the USB plugged in but as Soon as I start up Eye TV it goes blank. I would love this to be answered and really need help, all is appreciated, thanks.
