Plex HDHomerun DVR "HD Only" resolution not working

For what it is worth, I have an HDHomerun and I too am experiencing this. Others seem to be experiencing probems as well, see: Plex DVR not recording shows

If dev is having trouble reproducing, it seems widespread enough that we could probably help with repro’ing. Please let us know if anything else is needed.

After not having many series record, I switched all recording to SD. It’d be nice to be able to get HD recordings happening again.
