That's not what I intended to express. Let me clarify:

For example, video cards with nVidia chips that provide HDMI 1.3, i.e. a/v transport over HDMI. These have a protected BIOS (using public/private key cryptography), and only players signed against that BIOS will be able to send HD audio/video from HD-DVD/Blu-ray discs over the HDMI connection.

In other words, of course you can send arbitrary video over HDMI (i.e. the DVI part of it), but if I recall correctly the current implementations of HDMI 1.3 on video cards don't provide a system-wide audio driver at all, i.e. you won't be able to send arbitrary audio samples over HDMI at all - unless you run a specific player which directly communicates with the (nVidia) video card protected BIOS, in which case you *can* send TrueHD/PCM over HDMI.
