The odds are very strong that it will be a D-10. That has been the base receiver for Directv for about a year now. You don't want a D-10-200 those are made by Samsung for Directv. Samsung's warranty service center CVE INC. in N.J. is worthless after 5 months with my HDTV receiver they finally replaced it with a new one. Seeing this is the DVR forum if you are replacing a DirecTiVO by Samsung a R-10 is the current Directv DVR.
