I have Charter cable in the Madison, Wi area. After doing a guided setup with cable only, none of my local HD channels show up, only the analog ones are there. If I do a scan for channels on cable only the local HD channels are found. If I check the guide it shows to be announced for the local HD ones. Now if I hook up a rabbit ear antenna to the Premier unit and do a guided setup with antenna and cable the local HD stations show up with the proper guide information on the antenna connection. My antenna is not good enough for reliable reception to leave this way. Seeing as most of my TIVO subscription cost is being able to use the guide for selecting shows, I have lost most of its value. So is the problem with Charter or TIVO? Where do I start? I have only had the unit for a week. Getting frustrated.
