>Yes, good point, when I took a look more into that, I found those points in regards to HDCP. When I looked at the article in reference of your message, I was mostly interested into that section: "...the only way to deal with your HDCP compliance problem is to buy a cheap HDMI splitter that ignores HDCP requests."

My take is you need to know whether the content you want to play requires HDCP compliance e.g. protected video content, gaming etc. It seems to me if that content requires HDCP compliance, then the source device won't even play it if the output device isn't compliant. In that case a non-compliant splitter won't help (as I understand it).
