The Samsung SIR-S4120R is the latest generation DirecTV TiVo satellite receiver/DVR. Satellite receivers with built-in hard drives have a unique feature compared with stand-alone DVRs—the ability to record DirecTV signals in digital form, resulting in a replay that is indistinguishable from the original live satellite broadcast. This unit has a 14-day guide and continually updates program data via satellite.
