Many of the shows I record are broadcast in two or more timeslots, hours or days apart. Unfortunately, I often don't get around to watching a recording until several days later. This means my opportunities to re-record an episode that didn't record completely have already passed.
Nothing worse than sitting down to watch a 2 hour-long mystery, only to find the recording doesn't have the last 10 minutes...
Therefore, I'd like the option to automatically re-record an episode whose recording was marked as 'interrupted'.
