Ok, so like many many many others, I have no signal, when using Xbox 360, in red showing in the capturing software when using HDMI. When using component, works perfectly fine!
It worked for a bout 2 minutes on HDMI but there was no image on the TV and the resolution on the capturing software was totally off, only showed the top left hand corner of the Xbox.
On the Roxio itself, the purple light appears and so does the HDMI light. On Device Manager, under Sound, Video and Game Controllers, it says 'Roxio GameCAP HD PRO'.
I've tried swapping HDMI leads, nothing :\
I've followed many suggestions, uninstalling everything and installing again, I've got the Feb update too, the drivers are up to date.
