We were able to identify 3 out of 4 agriculture/business/news programs that always say "repeat" so any series set up to record them never will even though they're new daily or weekly. I'm not entirely sure what makes that distinction but, here's the programs and their genre:
AgDay
Newsmagazine
This Week in AgriBusiness
Bus./financial / Agriculture
Agweek TV
Public affairs
As far as I know, these episodes are always new. They're like local news broadcasts...but specialized.
