EPG (electronic program guide) aquisition can work using low-bandwidth methods if the box can stay on all the time. This low-bandwidth method could be a broadcast to all boxes constantly. So if your goal is a two-week EPG the box has to stay on for quite a while until it has seen all two weeks' data, and to process that you need to store it on the HDD. Such a box is going to be running close to its normal power requirement while doing these things.
