Self-assignment - bug?

[r-barnes]

This line is a self-assignment. Is this a bug? If not, can it be removed?

  if( FrmStat->FrameIdx )
      mvdX = mvdX ;

Thanks for pointing this out. I'm not sure what the original intent of that line was, and the original developer is no longer active. But it seems to be a no-op essentially.
