I am using 2 HDHOMERUN tuners (HDHR3-US and HQHR-US) with the latest version of Plex on a Dell Server running Server 2012R2 and I tried several time to record multiples program simultaneously but there is always only one recording at once. Any help??
Update your PMS to 1.7.2.3878 and then try again, if you have issues still please post your Plex Media Server and Plex Tuner Service logs.
