I've been noticing that about 90% of what I watch comes from local channels that I think all have digital broadcasts. These would be the local PBS, ABC, CBS, NBC and Fox stations. It seems like a bad idea to pay $80/mo for DirecTV (HD) if I can get the HD on those stations for free over the airwaves and record the content to my computer (which is already connected by HDMI to the HDTV) So I'm wondering if any of you are doing this -- can you get good signals over the airwaves with no antenna outside the home? I'm also wondering about using the Ubuntu box as a DVR. Apparently there is this thing called MythTV, but I don't know much about it, yet. Is it possible to add DVR capability to an ordinary Ubuntu 10.10 installation? Mike
