I'm not having any success getting the below line to run in Cron. I've added / before % due to it being a special character. It works without the / when run directly from Terminal.
Eventually I'd like to run a recording from 11pm to 7am so am open to better suggestions. OS is Ubuntu Mint on an R-Pi3 Class10 32GB SD.
