I reported earlier in this thread that after running a check switch (as instructed by advanced tech support), my 722k was no longer experiencing a sluggish guide. Ten days after running the check switch, I experienced a sluggish guide moment this past weekend. But I left the receiver alone - no reboot, etc. I left the receiver and TV on, walked away for an hour or so and when I returned the guide was responding normally. Last evening, sluggish guide again, but I was impatient so I hit the reset. As I reported earlier, Dish has flagged my account for a replacement receiver if I call again w/ a problem - because I have exhausted all of their troubleshooting options. However, several have posted here that the receiver is not the problem. I really don't want to go through the hassle of swapping out the receiver - not to mention losing some programs I've DVRd. Plus, if a new receiver is not going to fix the problem, I'll just keep what I have. Is there the risk of NOT getting a 722k in return but a regular 722 or other similar HD DVR? What would YOU do?
