Stressing out over taxes? Sure, a new half dozen HD channels on your EPG isn't apt to solve your problems, but at least you'll have something to look forward to when you're done fighting the lines at the post office, right? Comcast has announced that six newcomers are headed to the San Francisco Bay area today: Sci-Fi HD, Food Network HD, Animal Planet HD, The Learning Channel (TLC) HD, CNN HD and AMC HD. Users in the region will also have access to over 400 high-definition on-demand choices, but the release does note that certain parts of Santa Rosa, Hayward, San Leandro, Sunnyvale, Los Gatos and Saratoga will sadly be left out of the upgrade. Here's to hoping The Man isn't holding you down, eh?
