I sent in a support request to TIVO about this issue.  It took a few days before I got a response.  That was a little disappointing since many companies are moving to speed up support responses (especially those via the internet).  The answer solved 90% of these channels and now I have guide info for almost all of the newly added HD channels.  I can still watch the few that don’t have guide info but I don’t know what is going to be on that channel in advance and can’t set up a recording.

The answer showed a short cut to getting to  Channel Guide setup.   There was also a bit that tells whether you are talking standard or digital channels.

For completeness, here is the info I recieved:

• Choose TIVO Central (usually by pressing the TIVO button)
• Select Messages and Settings
• Select Settings
• Select Channels
• Select Channel List
• Press the ENTER key
• Follow the onscreen instructions.  The TIVO will ask questions regarding your channels and service.
• Ensure that you enter the proper zip code.
• Ensure that you enter the proper provider for your service.
• In the screen directly after you enter your cable provider, press the ENTER key.  This will take you to a list of available lineups.  In my case, I needed to choose <DIGITAL>.
• You will be given an opportunity to review the line up after you chose (note: it will not have the premium channels like HBO)
• Answer the remaining screens based on your service.
• It will take 10-30 minutes to reset this data so go do something else.
• Finished
