Good day all,

As the title suggests, I am looking for a way to disable HDCP in Windows XP 32 bit.

The reasons for this is I have just purchased a new capture card (NZXT 4K30) and intend to use it to capture gaming from my Retro Build via a Dual PC setup to my modern Windows 11 machine.

I have a DVI-I (Dual Link) to HDMI cable running from my Radeon X850XT directly into the NZXT 4K30, however when adding the video capture device in OBS Studio, the image is purple and green and distorted. see image: Imgur OBS Scene

From what I have read online this is a symptom of HDCP being enabled on the Retro machine.

I have scoured the web and cannot find a means of disabling HDCP in Windows XP, so I am looking here for help. On modern operating systems the new Radeon drivers simply have a toggle to turn off HDCP under the "Overrides" section, and for Nvidia users there is a registry edit that you can perform see here: Disable HDCP via Regedit
My only other option is to use a cheap VGA to HDMI converter and thus convert the analogue VGA signal to HDMI and capture that, but I would really like to avoid doing that and use the DVI-I to HDMI cable instead.

Any help would be greatly appreciated.
