I had my TiVoHD hooked up for the last few days, operating it without a cablecard. The TiVo is connected to the TV via HDMI. I was able to get HD locals and a few other digital channels just fine. Tonight, I had cable cards installed, and now get a message that I can't use HDMI with my HD channels, including HD locals because my TV doesn't support HDCP DRM. If I disconnect the HDMI and connect via component, it works fine. Why would using a cable card suddenly cause this to kick in? I didn't have guide data for HD locals before, but did have the channels. Is it something in the guide data then that tells the TiVo it can't use HD channels with a non HDCP tv?
