+The DVR entry is used by Tvheadend to keep track of the upcoming, 
+finished and failed recordings.
+
+* Upcoming and currently recording entries remain in the 'Upcoming/ 
+Current Recordings' tab.
+* When a recording completes successfully the entry gets moved to the 
+'Finished recordings' tab.
+* When a recording fails or is aborted it gets moved to the 'Failed 
+recordings' tab.
+
+Some entry details are not available/incomplete until the recording 
+completes or fails, e.g. filesize, total data errors, etc.
