Here is an answer at random to your secretive question.
Your recorder may be a Top Up TV recorder or may not be. Top Up TV used to broadcast a 14 day programme guide, but permanently ceased broadcasting on 1st November 2013.
Owners of Top Up TV recorders have reported on-line that they have successfully looked through the on screen menus and found the setting to change from the defunct 14 day programme guide to the 8 day freeview programme guide.
Immediately after changing the setting so that the 8 day epg is a Top Up TV recorder owner should be patient. It takes time before all the epg is populated without any gaps. The epg will only contain programme details as in the UK it does not contain program details.
You are very mysterious. There are many DTT receivers, each have their own foibles.
You have not said what the make, model and software is for yours. The how to mend it question box does remind questioners to state the make and model as that will help other owners and attract a better class of answerers.
