[mythtv-users] Unusual Audio/Video lag on an AMD64 3000+

Slight problem... How do I run a .pl file? (I'm new to linux)

and where is the cron usually located? daily.cron?

thanks,

Hmm... so maybe that could be causing the lag on the liveTV? I'll fix it and
see what happens.

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.
