OTA and Cable Card Tuners?

Currently migrating for MCE to Plex. For multiple tuners, do they have to be the same type? Is there a way or plans to support OTA and a Cable Card configured at the same time. Currently my MCE setup is running with a HDHomeRun DUAL and a HDHomeRun PRIME.

I only have one so I can’t try it but in the server settings you can add multiple Live TV/DVR devices.

See the Frequently Asked Questions – DVR & Live TV.

Under section Can I add more than one DVR tuner?
Multiple tuners can be added from within the Plex Web app, provided you are using version 2.10.5 or newer. Tuners should be of the same type; all OTA or all cable, on the same Plex Media Server.

I am unaware of any plans at this time by Plex to allow different device types to be configured in the same DVR.

This is really about the channel lineup. If you use the the cable card for some content and the other for clear qam it should work as long as the channels are on the same number. I was doing this for a while with a prime and a Hauppauge 2250.
