DISCLAIMER: DO NOT USE THIS METHOD FOR RECORDING MOVIES. INFRINGEMENT IS A VERY SERIOUS CRIME AND IS PUNISHABLE BY FINES AND JAIL TIME.
Those of you who've picked up a PS4/XBOX ONE might've been dissapointed when you found out you can't capture them. (Note:I only have a PS4, but this should work on Xbone as well)
1. Have a desktop screen recording software. (DXTory, Fraps, Bandicam, etc.)
2. Connect your console, you should see the preview in the Roxio application.
3. Record this preview (you should probably go fullscreen, however you'll need a good computer for this)
And there you have it! Now, this probably won't work on the average computer well, the video will be laggy thanks to Roxio's ABSOLUTELY amazing and reliable, highly-optimized software, coupled with an average computer. For now, I use the built in recording for the PS4, but the patch that allows Devs to change HDCP is coming soon
