Definitely needs fixing.  You'll want to run optimize_mythdb.pl (which
you should probably run in a daily cron at a time when recordings are
least likely to occur).  Then, you'll need to repair the seektable for
any "broken" recordings.  You can determine if a recording has a broken
seektable by trying to jump or skip forward.  If it takes time to do so,
you have a broken seektable (and, the longer you skip, the longer it
takes to skip).

To repair the seektable, use mythcommflag --rebuild.  (For some types of
recordings, i.e. ATSC or DVB recordings, you may need to use
mythtranscode --buildindex, instead.)  Search the archives for command
lines you can use.  Also see mythcommflag --help or mythtranscode --help.
