Your other replies may not have allowed for this file being in nuv/mp3 
format.  It's many years since I saw a file like that and I don't know 
the state of MythTV's support for it now.  Maybe vlc could play it.

And IIRC playback isn't usually dependent on the seektable - it's mainly 
used to help seeking.
