I Installed my Tivo Premier XL in February. Comcast cable went all digital in March. I am still getting many messages relating to channel changes and Comcast either doesnt know they are happening or cant keep up with them. I tried to get a list of channels I receive and the changes keep coming. That is not my issue though. My Premier is hooked up to my 52" Toshiba LCD (since February) via the HDMI cable and has worked watching live HD tv and recording HD shows. Been able to view recorded shows - no problems. Today, I turn on my Tivo and get this message: "The TV or audio receiver is not compatible with HDCP rights management standards. Unplug the HDMI cable between the DVR and the TV or audio receiver. Use the supplied component video cable instead to connect video from the DVR to the TV..." Can anyone explain what has changed to cause this? Last night everything was fine, today I can not watch live TV, cannot view recorded shows.
