I have been watching broadcast HD channels 702, 703, 705, 707 and 709 on my HD Tivo in the Bay Area for years and recently I no longer get 2 of these channels dues to 'digital migration'. According to Comcast support once my account is audited I will no longer get any of these channels unless I upgrade to a 'preferred' account. I checked the Comcast page for my zip code and sure enough, limited basic does not offer broadcast HD channels anymore. Only digital preferred and digital premier, which I don't need. What are my options? Do I have to use rabbit ears to get the digital signal outside of Comcast or is there some way I can get broadcast hd channels through Comcast while keeping my limited basic account. Thanks for any info.
