Be careful on your terminology, you mean Component video, not Composite (single yellow RCA plug). It sounds like your HDMI converter is not stripping out the HDCP signal so the video is being blocked. This can be a bit hit or miss when you buy a converter as stripping out HDCP is not something the manufactures will advertise as a feature. We know the HD Fury series work, and the Gang Hu one recommended by Sling Media, and I recently saw a post from someone who found one on Amazon that worked, but I didn't take down the details. You might find if you search.
