Do mean to say that this happens on every first attempt to play a
specific file? If so, this is highly unusual. Where are those video
files located (e.g. on an NFS or SMb share? How is it mounted? On boot
or per automounter)?
Please try to run

  'mplayer -identify vo null -ao null -frames 0 /your/video.avi'

and post the error message.

Possibly. Try to set USE_SPEED="false" and see if that helps. If so,
please report back.
