sieht so aus, als ob hdcp in keiner aktuellen (und auch alten) Grafikkarte unterstützt wird:
Although ATI has had “HDCP support” in their GPUs since the Radeon 8500, and NVIDIA has had “HDCP support” in their GPUs since the GeForce FX5700, it turns out that things are more complicated -- just because the GPU itself supports HDCP doesn’t mean that the graphics card can output a DVI/HDCP compliant stream. There needs to be additional support at the board level, which includes licensing the HDCP decoding keys from the Digital Content Protection, LLC (a spin-off corporation within the walls of Intel). After some investigation, Brandon and I determined that there is no shipping retail add-in board with HDCP decoding keys. Simply put, none of the AGP or PCI-E graphics cards that you can buy today support HDCP.
Aber es kommt noch besser: Ein "upgrade" auf HDCP wird für bestehende Grafikkarten nicht möglich sein, da die registration codes für hdcp im manufaktur-prozess integriert werden müssen:
An ATI representative said: “People will not be able to turn on HDCP through a software patch since the HDCP keys need to be present during the manufacturing. We are rolling out HDCP through OEMs at this time but we have not finalized our retail plans yet.”
Well, what about NVIDIA? They were actually very direct: “The boards themselves must be designed with an extra chip when the board is manufactured. The extra chip stores a crypto key, and you cannot retrofit an existing board after the board is produced.”
... und das, wenn im März HD-DVD und BD-Disks mit Hilfe von PC-Laufwerken abgespielt werden sollen: http://www.heise.de/ct/06/04/032/
