According to the folks at Samsung only 3 companies are producing D* boxes and they are being produced to D* specifications. Those specs do not include simultaineous SD and HD outputs so none of the new boxes will support this feature. So nether the Samsung ( which was the first to output both formats ), RCA nor Hughes branded units will output both a the same time.
