Comment (by anonymous):

 Thank you for working on this.  Here is some information to help you out.

 I'm using a HdHomeRun to record into mythtv.  I'm using mythicalLibrarian
 to export my recordings to XBMC.


 Episode file used for testing: /home/mythtv/Videos/Episodes/Caprica/Season
 1/Caprica S01E11 (Retribution).mpg
 mythtv reports recording duration of 49 minutes 33 seconds. XBMC reports
 59 minutes 57 seconds

 Comskip version 1 file:

 Here is a picture of my desktop which shows many different readers reading
 the same file.
 [[Image(http://i236.photobucket.com/albums/ff111/DrivingTibNaked/Screenshot-1-6.jpg)]]
 Top left My Windows virtual machine without proper codecs with Windows
 Media Player, you can see it displays 59:56.
 Bottom left My XBMC-Live media center in VNC :0, you can see that it has
 59:57.
 Top right of left screen Mac OSX virtual machine had problems playing the
 file.
 Bottom right of left screen, Ubuntu Media Player displays 1:06:05 for it's
 runtime.
 Top left of the right screen, you can see a VNC into my media center on :1
 with actual MythTV playing the file and it displays 49:33.
 Bottom of right screen, you can see a terminal into my XBMC-live
 displaying ffmpeg. runtime: 59:57:31
 Far right top of left screen, you can see a terminal displaying the files.

 Bottom line:  I think MythTv is using comskip information or some other
 method of calculating the runtime.  The runtime is wrong, but the comskips
 match up with the improper runtime.
