my computer has an nVidia 9800GT graphics card (HDCP compliant) that i run to a 24" samsung computer monitor (HDCP compliant).  the graphics card has dual DVI outputs, with a converter accessory that can convert one of the outputs from DVI to Component.  i just bought a Blu-ray drive for my computer that i've been using to watch movies.  i wanted to run the second DVI out to my TV (non-HDCP) via the DVI -> Component converter cable.  now i know HDCP only works through a digital connection, and since Component is analog... i was hoping i could watch my Blu-ray movies on my TV without having to worry about HDCP issues.

Putting this in Basics probably wasn't the best bet for attracting attention from people with the right kind of expertise. I'll move it to Computers and HTPC.

First a couple bits of background information that may be useful.  Most versions of DVI contain both digital and analog signals.  HDMI contains only digital signals.  HDCP is a digital copy protection scheme, not analog.  I'm guessing your converter is not actually converting the digital signals to analog (because such a device costs hundred of dollars), instead it is just lifting the analog signals from the DVI connector and outputting the signal to RCA type connectors.  To be compliant with copyright law, the manufacturer of a device is not permitted to circumvent copy protection.  Allowing the analog portion of a DVI connection to receive the signals of an HDCP encoded source would be allowing circumvention of the copy protection. My guess is your video card turns the analog off when HDCP content is played.
