Changing from marked new

I have googled all over for this answer, but have found nothing on the topic. I simply need a way to change a show from being marked new. The frustration stems from shows which I record all episodes of, and keep a few for long term. If I save one that is marked new, then that show's main folder states I have a new episode inside. Therefore I scroll to that folder, only to find its an episode several months old that I have saved. Isn't there a way to change a show that we have watched from being flagged as new?



I have a TiVo premiere using OTA.
