Update: Just noticed a movie started recording twice. Half an hour after 
the movie started recording (no description available), a new recording 
starts, this time with description and end-time 53 seconds later than 
the previous recording. I don't have the program table from before the 
movie actually started showing, but currently it shows:

  +--------+---------------------+---------------------+-------------+
| chanid | starttime           | endtime             | title       |
+--------+---------------------+---------------------+-------------+
|   2002 | 2010-07-07 15:39:29 | 2010-07-07 17:15:53 | Dilligensen |
+--------+---------------------+---------------------+-------------+

My guess is it originally showed 15:40:00 to 17:15:00. At least the 
first recording (including two minutes hard padding) started recording 
at 15:38:00, and is set to end at 17:17:00, also with two minutes hard 
padding.
