A variation on the theme: I have two 622's, both got replaced within three days. First one, which was the very first generation 622, bad HDMI port, etc., had worked fine until I replaced the Smart Card. After a few weeks of rebooting itself two to three times an hour, DISH sent me a replacement. Then, in a strange chain of events, in which DISH de-activated my second 622 while activating the replacement 622 for number one, the DISH tech they sent out to deal with that issue (which we didn't realize was the problem at the time) was having so much trouble getting ViP 622 #2 to download the program information that he gave up and replaced it from his truck..
