I need help dealing with direct tv and their equipment. I had a samsung sir 4080r for 5 years, but it appears that the hard drive is going out because the unit reboots itselfs daily. So I got a new unit from direct tv R15-300. Is there a way to watch 2 shows at the same time without recording one of those shows? With my samsung I could have 2 shows going at the same time without recording. When I talked with direct tv they said they did not allow customers choose their replacement units and suggested that if we wanted a different unit than what they sent us we should go to a direct tv retail store and purchase one. Any suggestions?????
