Hi, I am also having this exact same issue.
Are you trying to record games from a PC to a laptop?
Also do you get a picture on your monitor?
I dont even get an image on my monitor but when I test other HDMI devices it works fine.
Even the "Guru" can't give me an answer to my issues.
I notice on my PC I am playing the games on has 2x HDMI ports 1 on the GPU and 1 on board. I also have a CPU which has an iGPU but my understanding tells me this is disabled when you use an expansion GPU on PCI-E.
I think that is the same rule for the on board HDMI.
I am coming to the conclusion it seems to be a compatability issue between the GPU and the Roxio device in what it supports.
No one seems to know and I have run out of ideas.
