My apologies if the subject of this message is a terribly newbie question. Also posted to Blu-ray software.

I've tried looking in all the usual places (including this forum) and haven't found anyone keeping a list of HD-DVD pre-recorded movie titles that turn on the HDCP copy-protection flag when sending via HDMI. (More apologies if I'm not using the right jargon or have my concepts warped.)

Am I to assume that ALL HD-DVD titles have HDCP enabled, or NONE of them do, or that no one has bothered to keep a list?

From what I know studios agreed not to use ICT on any HD DVD or Blu-Ray titles until 2010 or 2011

Edit: ICT won't be a problem until then, which is the downscaling of HD video to SD

Maybe I'm wrong here, but I believe that HDCP is a hardware implemented, not software...

from: http://en.wikipedia.org/wiki/HDCP
HD DVD, Blu-ray Disc and DVD players (with HDMI or DVI connector) use HDCP to establish an encrypted digital connection. If the display device—or in the case of using a PC to decrypt and play back HD-DVD or Blu-ray media, the graphics card (hardware, drivers and playback software)—does not support HDCP, then a connection cannot be established. As a result, a black picture and/or error message will likely be displayed instead of the video content.

Is is possible that you are confusing HDCP with Image Constraint Token (http://en.wikipedia.org/wiki/Image_Constraint_Token)?

They are ALL HDCP flagged.

HDCP is enabled on all Blu-Ray and HD DVD players. That is why your HDTV has to be HDCP compliant to be able to use the HDMI input. HDCP is hardware implemented not software based. When you turn your player on, it talks to your TV and makes sure it is HDCP compliant. If it isn't, it will not allow an image to be displayed (at least that's how I understand it).

The copy protection that is on HD DVD/BD is AACS and, yes, it too is enabled on pretty much every HD DVD and BD.

I think what the op was really wanting to ask about is the ICT token that, when enabled, will downscale all HD resolutions to SD (480p) when using component cables. This has not and should not be enabled until at least 2010 or 11 (as mentioned above).

And, for your reading pleasure, here's a short description relating HDCP, AACS, and ICT, from the web site:

http://en.wikipedia.org/wiki/Advanced_Access_Content_System

Plugging the analog hole

AACS-compliant players must follow guidelines pertaining to outputs over analog connections. This is set by a flag called the Image Constraint Token (ICT), which restricts the resolution for analog outputs to 960×540. Full 1920×1080 resolution is restricted to HDMI outputs with HDCP (when the ICT flag is set). The decision to set the flag to restrict output ("down-convert") is left to the content provider...AACS guidelines require that any title that implements the ICT must clearly state so on the packaging.

So, AACS interacts with the HDCP specification over the HDMI hardware interface to guarantee that encrypted digital video stays protected until it is decoded in the display device. It looks like AACS is used to "feed" encrypted content through HDCP and to impose the ICT over analog component when the ICT flag is present on a disc (which it isn't for any release so far).
