They probably do exist, but as with most combination units, it would be more expensive to get than to just buy a dvd recorder and hook it into a High Definition tuner. I have a Lite-On Recorder which record in +R +RW or -R -RW fomats. It also records audio cd format and SuperVCD format on any CDR or CDRW. It's hooked up to a Motorola DSR-550 Voom receiver through an S-video wire. My receiver is set to stretch (not zoom or letterbox) 16:9 material to fill oblong into a 4:3 ratio. I play it back on a Widescreen television and set the dvd player to correct the aspect ratio, and it displays a high quality SD image in 16:9 ratio.
