Mark:  Thanks.  I'm not too worried about the previews, but something is 
peculiar.  It seems that for *any* 1920x1080 h264 recording that I have 
tried, if I rename the preview file no new one is created.  New HD 
recordings don't have preview images.

For 544x576 h264, previews come back when needed.  Intermediate 
resolutions still unpredictable.

If you don't have recordings that do this I can post a clip.  I haven't 
done a backtrace recently.
