Comment (by lennie):

 It is difficult to tell how many frames are being shown with the Canon
 viewer/editor (it has about 1 second granularity in "seeking" and
 "status".  I can tell you that the artifacts tend to occur at the start of
 videos - but do have one clip where it happens near the end of the clip.
 Another clue is that this doesn't happen on many clips.  I shot about 1000
 clips of 5-20 seconds and only about 4-5 had artifacts like this.  I
 suspect that the Canon Powershot camera is using some fields/features
 which are not supported by ffmpeg/Mplayer as well as Quick time - I was
 very surprised when I used the Canon .MOV editor (and exported to an .AVI)
 that the video appeared normally (with no artifacts).  That is how I got
 the DVD authored but want to track down where the error is (and how the
 Lead Tools .MOV decoder doesn't have problems).  I also have a ticket with
 Canon support to see if the problem is on their side but wanted to see
 what the Open Source community could do to fix/explain the artifacts.
