The only 1 cable solution that carries both audio and video signals, including HD signals is an HDMI cable. However, there is a 99% probability that your DVD recorder does not have an HDMI input! 99.9 % of home theatre electronics for recording (DVR, DVD-R, and such) don't allow the recording of HD content. The exception to this is OTA broadcasts from Public Television. Recording HD OTA broadcasts is possible with a DVR that has an ATSC tuner built in. If you were to ask if there is a way to pump HD audio and video signals from a Coax out to the ATSC Coax in... the manufacturers have already thought of it, and that does not exist either to date as far as I know. With the amount of data that HD movies and HD sound contain, a 2 hour program would not fit on a dual-layer DVD +R, -R, or RAM. That is why HD-DVD players and Blue-Ray players have entered the home theatre arena. If you were to say, "But my DVD recorder supports 720p and 1080i"... that only means that the *player* functionality UPCONVERTS the 480i signal on the disc, to a decent picture that seems to have the look of HD quality.
