Please support some sort of multirec feature to allow recording subchannels of a given channel off of the multiplexed stream from a single tuner.
As discussed in the following thread:
There are very good reasons why we sometimes need to extend the recording time for a particular show (see the existing, valid option to begin early or end late). These overlaps are causing some scheduling conflicts that would not exist if the software was able to record multiple subchannels from the multiplexed stream of a single tuner/channel (see https://forums.plex.tv/discussion/324331/bug-the-scheduler-fails-to-properly-handle-a-short-time-overlap-conflict-between-channels/p1 for a related bug in conflict handling).
Please see the following for a more detailed description of the capability as added to MythTV:

By not forcing a subchannel onto a separate tuner, conflicts can be reduced when shows share a common channel frequency.
