First off, my specs:
Windows 7 Home Premium, Intel i7-4770K, Dual Titan X, 20GB of RAM (for video editing, C4D, Maya etc etc)
Using HDMI in and out.
Anyways if you look at my post history you'll see I have had issues with this device in the past, so I just stopped using it for about a year. I decided to fire everything back up today and reinstall the software (updated to the latest version) for good measure, make sure all my cables were good (they were), Windows recognized the device and I thought I'd actually have a smooth experience.
Well, behold: https://drive.google.com/file/d/0B2ew-jnhjd5yRFhJMUl0ejBYRTQ/view?usp=sharing
I tried using different USBs, restarting, reinstalling again, even wiping Windows completely. Still the same problem. Everything is fine if I close the capture program, it passes through fine. As soon as I open it, the problems start. I've tried pretty much every solution (well, not for me) on this forum, inlcuding changing graphics card settings and the like.
