We just got this receiver a month ago and from the beginning it has been recording shows that are not listed in the Timers section. It happens, over night, when the tv's are off. We have the updates set to download around sometime between 5 and 7 AM, not sure when. It seems like it is around that time that it records programs on its own. Sometimes they are 5 minutes sometimes over an hour..it varries. They are always programs that we never watch...sometimes infomercials, sometimes kids programming, random things with no logical connection. If we have something set to record, say around 8AM, it will usually skip it.
