i'm with you Frank7004
10 622's in 4 years and hard drives on earlier dvr's?!? you are more likely to get hit with a meteorite than to have that many factory defects. the 622 reciever runs kinda hot to begin with, i think that makes it more vulnerable than the 722k. i would be certain that you have a bad section of cable or connector and the "short" is overheating you recievers and causing the other failures. maybe start with the cable from the dish to the groundblock. check for nicks or exposed braiding( especially if it comes off the roof, at the edge of the roof).
