The best you could hope for from a DVD
recorder is that it would downconvert an HD signal to DVD quality (which is better than analogue NTSC quality) for recording on DVD, then upconvert it for playback. The results could potentially look as good as an upconverted commercial DVD. But that's the best possible scenario, reality probably wouldn't be as kind.
If the DVD recorder has a hard drive, then ideally it would be able to record the HD digital signal directly to the hard drive and be able to play it back directly as well, resulting in full HD resolution. It would only downconvert if recording to a DVD. But again, I don't think you're likely to see this on the first generation or two of ATSC-equipped recorders.
If you want to record full HD quality to optical discs you'll have to wait for an HD-DVD
recorder, which will be considerably more expensive both for the hardware and for the media.
