My cable set top box (Scientific Atlanta 8300HD) is connected to my plasma display (TH-42PWD8UK) via HDMI and also to my Tivo PVR via S-video. When I place my display in standby mode, my cable box outputs a message to all outputs saying "Copy protection, The DVI/HDMI output is blocked. Press cancel to exit.". I think this is occurring because when the display is in standby mode it stops responding to the HDCP messages coming from the STB. This causes a problem when the Tivo PVR records a program while the display is in standby mode since all that is recorded is the message saying "Copy protection. The DVI/HDMI output is blocked. Press cancel to exit."
I think what is needed is for the HDMI input card (TY-FB7HM) to stay running even while the display is in standby mode so that it can then respond to the HDCP polling that the STB is doing every few seconds. Alternately if there is a way for the display to gracefully shutdown the HDMI connection to the STB so that the STB will just disable the HDMI output without displaying a message this might work as well.
Does anyone have any suggestions for fixing this problem? I'm using component outputs right now, but my in-wall wiring is HDMI, so I need to switch to in in order to locate the components in the proper place.
