I set up a 30 minute manual record to record weekdays and have maximum recordings set to 1. It records on all the days that it should, but keeps every recording until I delete each one. (I am recording the local morning news for 1/2 hour weekdays and only want the current days news to show up on the DVR recorded list. I may or may not watch every day and may not finish watching all at once.) Am I missing the point of "maximum recordings" or is there something wrong with my machine? I have had the 722K for 2 weeks.
