I have the same problem. I have an HDMI chord running from my Xbox 360 to the device and from the device (with another HDMI chord) to my HDTV and the USB from the device to my laptop (which I installed the disk on successfully) and I get a white screen on my HDTV (which is normal for no input and it says "NO SIGNAL") and a black screen on my software with no sound coming out of my laptop or my HDTV. I've already checked all the wires and the device has recognized that I'm using HDMI and I don't know what to do. What I'm wondering is if the device is defective or if I'm just doing something obviously stupid. I only just bought it from Future Shop, I plugged it in (after I installed the disk that is) and it didn't work. If you need me to clarify anything just post it, I will be checking this page daily.
