What you just said, what did it mean?
To allay movie company fears of piracy people selling pre-recorded movie playback devices (like DVD players) are contractually obligated to copy-protect the output (a DVD player must enable macro-vision on protected DVDs).
Assuming no change from historic practice at some point this will mean that all HD-DVD/DVHS digital outputs need to be encrypted (HDCP) and analog outputs can contain no more than about half the pixels of a 1280x720 source and a quarter of the detail from a 1920x1080p recording.
If you have the external DVI-D to VGA converter or player with analog outputs you'll only be able to display your HD sources on your CRT projector with a bit more sharpness and detail than PAL 16:9 enhanced DVDs.
If you have the input board from this thread, HDCP keys for it, and the licensing people agree it can't be used outside a projector you'll watch your movies with as much of their HD glory as your projector will resolve. I'd buy that for $200 or more.
With an HDCP key, the board, and implementation the HDCP license regards as having "analog outputs" because it's too easy to use outside a projector you'll be stuck with the reduced resolution and might as well use the player's free analog outputs.
With no HDCP keys the board will become worthless for pre-recorded HD material. You'll need to replace it with an outboard decoder.
