The ability to either choose multiple channels to record a show from or, alternatively, exclude certain channels would be very useful.
I currently record several cooking shows from PBS. There are 3 different channels available in my area which might broadcast shows I would like to record. This would be fine except now I’ve managed to create and add my own curated channel to the guide which replays all these continuously, and it seems silly to record a recording to Plex which is being pulled from Plex itself already.
