Hi,

My problem: error message when playing blu-ray movies stating that the HDCP encryption could not be established.

My setup:

  1. A new projector (EPSON EMP TW700) with a HDCP-compliant HDMI port
  2. a PC with a brand-new graphics adapter (Sapphire HD 4350 512MB DDR2) supporting HDCP
  3. Connection made with a DVI cable (it's installed in my wall) and a DVI-HDMI adapter to connect the projector
  4. Latest drivers and software

My questions:

  1. What can I do to establish the HDCP connection?
  2. Would it help to use the HDMI output of the graphics adapter instead of the DVI (could it be that the HDCP chip is only supported on HDMI?)
  3. Any other ideas?

I am very thankful for any hint.

    I'd like to connect my PC to an HDTV using an HDMI-HDMI cable. The distance between them is about 8 m; is the length going to be an issue? I'm worried the signal might deteriorate over such a distance. Also, does price have any major impact on the signal quality? I'd like to buy an 8-10 m cable for… >>> More
