 Did a pastebin of the output from mythtranscode

  http://paste.ubuntu.com/13191547/

 This only seems to happen when transcoding video files that have a .ts
 extension.   I have tried both with and without cutlists and that makes
 no difference.  Transcode of .mpg files (the very few that there are) work
 correctly.

 Recordings were made from a Hauppauge HVR-1600 capture card on MythTV
 0.28

 mythfrontend --version shows:
