This article on anandtech surveys the current hdcp capable graphics cards:http://www.anandtech.com/video/showdoc.aspx?i=2874
They tested using a pioneer blu ray drive and powerdvd 6.6 BD. I found a couple of key points in the article:
"If any one of your hardware or software components within this chain does not support HDCP, then your Blu-ray or HD-DVD movie will not play. Most of the time an error message will pop up and give you an idea of what is wrong; If the graphics card is not HDCP compatible, PowerDVD gave us an error message saying, "fail to enable HDCP. Please switch to analog output (VGA, D-Sub) and try again." If the graphics drivers were incompatible, we got an error message along the lines of "please make sure your graphics drivers support HDCP." These are both fairly straightforward error messages, and for the most part, we were able to tell where the chain was failing whenever we had problems.
If the graphics card itself didn't properly support HDCP the result was a bit more in your face. For instance, we had a X1600 Pro sample with an HDMI port from Sapphire which was listed as being HDCP compatible, but we tried to play our Blu-ray movie we were greeted with a screen full of static.
and then the conclusion:
Because HDCP and accompanying technologies are so new, we encountered problems or quirks with a few of these cards. Some of the cards, like the HDMI Gigabyte 7600 GS and ASUS EN7600 GT, were only able to play our Blu-ray movies over HDMI and not through the DVI port. Conversely, we found that with our MSI NX7600 GT Diamond Plus, the Blu-ray content wouldn't play through the HDMI connection but it would through the DVI port. These issues can generally be solved by converters, but it's still a bit of a nuisance. Unfortunately, an HDCP key ROM is required for each display output in order to allow protected content to play over both. Oversights like this should be remedied in the future (at the expense of either the manufacturer or the end user). For now, consumers should be aware of the situation.
The take away message is clear, you can re-purchase your movies, you can purchase new playback drives, a new videocard, and a new dispaly and you still will not be able to view high definition video.
The MPAA claims a loss of 6.1 Billion dollars in the year 2005http://188.8.131.52/search?q=cache:...ient=firefox-a
A loss of 6.1 billion dollars each year makes a strong case for needing much stronger content protection than even what hdcp gives. With the adoption of internet access in consumer homes almost 75% perhaps all consumer electronics could be required to receive playback-authorization from a central authority everytime you used them.
