I'm not sure about the Hopper, but I have seen other Dish receivers having problems with timers not firing the first couple of days after the initial install. I always thought it was due to not getting everything needed to operate downloaded to the system. Same as it taking up to a couple of days for OTA guide (yes, i know Hopper does not have this yet), VOD and BB@Home not being available for the same amount of time. This has been my experience, I'm sure more knowledgeable posters could give better info on this than I can.
