Plex cannot use any kind of storage that is connected to an HDHomeRun. You need something that can run the Plex server, whether that is a computer, NVIDIA Shield TV, or NAS. Plex can use a USB hard drive connected to that device.

There was a typo in my previous post. I meant to ask if Flex contains software to record to USB HDD. Spellcheck changed Flex to Plex.

My current system does not work well with DVR function in Plex.
