I checked the log and there is a Damaged Recording entry for the program listed in Yellow.  So I watched the start of the program and it’s okay, but have not watched it completely.  

If another airing of that same program occurs it will be recorded, but what if I’ve watched it and it was minor damage, and I deleted it. Is that where the delete and allow recording again vs. don’t allow re-recording?
