O.K. well, I appreciate the help in this thread but I still haven't resolved my issue.
After many unsuccessful re-installations I still have the "Unknown Device" issue, and I still have the issue in which my Roxio device is not picking up a signal from my video-card's mini-HDMI output.
It is not the cable. When I plug the HDMI cable directly from my video card into my monitor, I get a working signal.
When I plug the cable into my Roxio device, and plug another HDMI cable from the Roxio output, into my monitor, I get no signal in either the Roxio software or my monitor.
I've tried several other USB ports and the same issue persists.
I have a few questions:
1- What devices are supposed to be in the Device manager? If I have one Unknown Device, and one Roxio GameCAP HD PRO, what is the Unknown Device supposed to be? I've seen people using the original Roxio GameCAP (Non HD version) and it shows TWO devices in the device manager.
2- I have 3 outputs on my video card. Two DVI outputs and one mini-HDMI output. Can these outputs be used together, or if one is being used does this disable the other outputs?
3- I'm curious if I have to set up a second display in my NVIDIA settings in order for the signal to be picked up properly.
4- Is there anything you could possibly think of as to why the device is not properly picking up my video-cards HDMI output signal, when it properly picks up my XBOX's HDMI output signal? I understand this device was made for consoles, but was under the impression it also worked for PC. Could this have anything to do with my PC hardware?
I am going to attempt to pick up component cables today so I can test those connections, rather than HDMI. I am going to pick up DVI -> Component cables and see how my luck fares. Thank you again.
