The Guide lists Headline News in the morning as a 4-hour show. I want to record only 30 minutes of the news. I've setup a recurring 30 minute manual record on the HLN channel so that the unit records 30 minutes every day from 7 to 7:30am. What I would like is if there is a way to tell the HR20 to only keep one recording so that it keeps overwriting itself (who needs to keep old news). Of course, this option exists if you're setting up a regular Series Link, but this option does not appear to exist for manually recorded shows. Does anyone know how to accomplish what I want to do.
