Hi,

 

HDCP in any version will not work with WATCHOUT or similar applications. Datapath can only support HDCP using their software with their graphics cards to ensure an encrypted path from source to display.

 

The idea with copy protection is to prevent recording or processing of a captured signal which is a bit contradictory of what WATCHOUT does.

The most common "work-around" is probably to use something like this in between:

While such a device defeats the whole purpose of HDCP, I'd guess that as long as you're not using it to make illegal copies of copyrighted material you're fine (but, as they say, IANAL).
