[mythtv-users] Trying to Understand mythcommflag --rebuild

I'm experimenting with removing commercials by following the
instructions at http://www.mythtv.org/wiki/Script_-_RemoveCommercials.
In an attempt to understand the script, I have been running the commands
manually on a HD recording of local news captured via ATSC.
The news cast is one hour in length. However after running
mythtranscode and mythcommflag --rebuild, the show is now reported as 17
min 23 seconds. The show is still there in its entirety but pressing
the 30 sec skip forward button actually moves forward around 2 minutes.
It is my understanding that the "mythcommflag --rebuild" command is
supposed to fix this by rebuilding the seek table. Is this correct?
And if so, what might I check to determine why mythcommflag is not
rebuilding properly. I've tried using both the "-f $DIR/$FILENAME" as
in the wiki and with "-c CHANID -s STARTTIME". Neither helps. I'm
running 0.21-fixes.
Here is the output of my mythcommflag --rebuild command:
mythtv at mythfe01 /tv0/record $ mythcommflag --rebuild -c 2581 -s
