DVR recordings almost never complete

I wish Plex would chime-in about this. Is this a known issue? Is a solution in the works? I just updated another firmware release for my HDHomeRun. I updated to the newest Plex version. I deleted the DVR and then created a new one. And last night, sure enough, 3 out of 4 programs recorded were partial. I wish I wouldn’t have spent all of the money on this configuration when it just doesn’t work (and hasn’t worked for months).
