[mythtv-users] Seek table wrong up after transcoding, --rebuild doesn't fix

[Patrick Quinn]

I'm trying to transcode files in order to remove their commercial cut
list, but when I view them after doing this, pressing skip+ or skip-
often skips way more than it should.  Oddly, skip+ and skip- often
jump to exactly the point where I cut out a commercial.

This is the sequence of calls I made (based on
http://www.mythtv.org/wiki/index.php/Script_-_RemoveCommercials):

$ mythtranscode --honorcutlist --showprogress -m -b -c 1004 -s
20070523210000 -o /multimedia/recordings/1004_20070523210000.mpg.tmp
$ mv /multimedia/recordings/1004_20070523210000.mpg
/multimedia/recordings/1004_20070523210000.mpg.old
$ mv /multimedia/recordings/1004_20070523210000.mpg.tmp
/multimedia/recordings/1004_20070523210000.mpg
$ mythcommflag -f /multimedia/recordings/1004_20070523210000.mpg --rebuild
$ mythcommflag --clearcutlist -f /multimedia/recordings/1004_20070523210000.mpg

and then some sql which correctly updated the file size and set
"cutlist" to "0" (see above script)

1004_20070523210000.tmp.map is sitting in my recordings directory
containing what looks like seek tables.

Below is the output from using mythcommflag --rebuild.  Any help would
be greatly appreciated.  Thanks in advance:
