Doesn't look like the Colossus supports HDCP.
The one I have doesn't. I guess they never added it.
Only other brand I know of is black magic design, but theirs are higher.
You could always use an hdcp stripper. I have some HDMI switches that do that with no side effects.
There's actually a very good chance I'll never use my Colossus cards or HDMI switches again. The ones I have stop at 1080i resolution though. Let me know if interested.
