New additions since the last post. Added a MyHD HDTV decoder card to my HTPC. KVM switch to control the output from three sources - iScan DVDO Plus (v2), HTPC, and MyHD HDTV Decoder card in the HTPC. Purchased a big VHF/UHF/FM antenna. Installed and wired it from the attic to the basement. Purchased a smaller double bow tie antenna for reception of some channels that I am not getting from the attic mounted antenna. I am working hard to get the available DTV channel in the Atlanta area. The only channels that I can tune in so far are NBC and Fox.
