[mythtv-users] Trouble removing ads with mythtranscode

Hello, myth-users.
I am having trouble deleting commercials using mythtranscode. Based on
the MythTV wiki documentation, here are the steps I'm trying to use to
remove commercials:
#1) I mark the commercials using the editing interface in mythfrontend,
or let the automatic process to it. The flags work perfectly for
skipping the ads while playing back in mythfrontend.
#2) I determine the file name of the recording, and choose a new name
for the ad-removed file.
INFILE="1045_20070411225900.mpg"
OUTFILE="stripped-$INFILE"
#3) I generate the cutlist. This seems to work fine, though produces
disturbingly little output. Where is the cutlist stored? In the
database? I thought this step would create the .map file, but it doesn't.
mythcommflag --gencutlist -f $INFILE
2007-04-12 16:08:53.200 Using runtime prefix = /usr
2007-04-12 16:08:53.326 New DB connection, total: 1
2007-04-12 16:08:53.338 New DB connection, total: 2
#4) I create a new, hopefully-shortened MPEG file.
mythtranscode --honorcutlist --mpeg2 --showprogress -i $INFILE -o
$OUTFILE
This process also looks like it's working correctly. That is, no errors
are displayed, and it creates $OUTFILE and $OUTFILE.map files. The
$OUTFILE is smaller than the $INFILE, but not by the amount that it
should be (I think the slightly diminished size is a result of
conversion from MPEG-TS to MPES-PS).
[root at media tv]# ls -l $INFILE $OUTFILE*
-rw-r--r-- 1 root mythtv 2091966464 Apr 11 23:31 1045_20070411225900.mpg
-rw-r--r-- 1 root mythtv 2036125700 Apr 12 19:04
stripped-1045_20070411225900.mpg
-rw-r--r-- 1 root mythtv 62330 Apr 12 19:04
stripped-1045_20070411225900.mpg.map
So each command LOOKS like it's working -- but the resulting $OUTFILE
still has the commercials! >-{
What did I miss?
Thanks,
