 If I run the same command with the filename quoted, the preview generation
 reports

 And after generating the position map

 The PNG are generated right but MythWeb does not display them also as the
 copies in the data cache folder but I'm not sure how the files from the
 recording folder end up in the data cache folder for mythweb.  Generally
 speaking, these functions should enclose the filename in spaces for each
 external command
