I'm trying to find a good HDTV DVR for over-the-air (rooftop antenna) signals and I am really getting no where with it. Some of my known, basic requirements: -Must be dual-tuner (record one show, watch another). -Must have a coaxial cable in for the antenna. -1080p preferred but 1080i will do (meaning HDMI/YPbPr output). -Must have a coaxial cable out as well (to TV). Basically the goal is get an HDTV tuner that will work on my old CRT TV and when I decide to upgrade that TV to a 1080p LCD, it will complement it with dual-tuner/DVR capabilities. $100-150 budget I am quite lost at this point.
