I can't seem to find an answer to my question. A few days ago Comcast went all digital in my area. Before Comcast went all digital, if we only subscribed to basic TV, local digital channels were in HD if you had an HDTV with a digital tuner. I have an HDTV with a digital tuner and an HD DVR with a digital tuner. On my TV, I have lost the HD digital channels, but my DVR they are still there. How can this be? What has comcast done to block the channels on my TV but not on my DVR???
