I have about 20 timers, mostly DishPass, all channels, set up on my 722. If I go to skip a particular timer event, it normally takes about 10 seconds to respond. Yesterday, the response time has increased to 30 seconds or more, and last night while skipping an event, it spontaneously rebooted, and then did the same thing this morning. I can't imagine that the unit is overheating as I installed a Thermaltake II fan exhaust fan on the left rear side of the unit over a week ago. I've had many more timers on my old 625 and never had this slow of a response before. Has anyone else experienced this with a 722? What is your normal response time with skipping or restoring a timer?
