Some Favorite recordings are missing padding.

I set a favorite's start time to "1 minute earlier". Some of the favorite's recordings have 1 minute of padding at the beginning of the recording, and some of the favorite's recordings do not have 1 minute of padding at the beginning of the recording. I have "Remove padding on back to back Favorites on the same channel" set to "yes". There is not any reason for SageTV to remove the padding, since there is not a recording scheduled before this recording.
