HDMI's initial version is electrically and pin-compatible (passive adapter only) with DVI-D single link; assuming the DVI port supports HDCP. The parent post is correct in that the mandatory HDCP was a major feature (for the involved cabal of organizations).

This is wrong. HDCP isn't mandatory to implement HDMI, they are two separate technologies. I'm not defending HDCP or DRM encumbered content but I wish folks would get their facts straight.
