Some DVD player/recorders are better than others at DVD playback. So yes, a player may have an advantage over a player/recorder. The British magazine, What Hi Fi, will do these DVD recorder shoot-outs from time to time and they pay close attention to DVD playback quality. Based on one shoot-out about a year ago, where they claimed that SONY trumped Panasonic and Toshiba due to playback quality, I went with a SONY RDR GX315 ($300 list, now available for $150 in most places). It does DVD recording; DVD playback; and CD playback all very well.
