My brother has DirecTV at a lake house. One of the DVRs, and HR21-100, is clearly going bad. Video stops/stutters, sometime freezes, unit has to be re-booted, etc. We even got a hard drive error message, code 14-023, yesterday saying try a re-boot. Other receivers in the house do just fine. He says he has called several times and they stall with all the trouble shooting steps and then say they will not ship a replacement unit w/o a truck roll. Problem is, he is only there occasionally. Is there any way to get them to send a replacement unit/recovery kit without a truck roll? Do they even want HR21-100s back? If not, perhaps try a dealer/installer in the local area (Clemson SC area). Also, all of this should be no-renewal commitment - unit is clearly faulty. Thx!
