Hi Mark:  Your latest post on this seems to have vanished from this box, 
and the F30 box with the HD recordings is now running master, where some 
new previews from HD have been created but with severe 'line-hold' 
problems; and when I tried from a konsole I got an omx complaint and a 
segfault.  Here's a clip that I made earlier.
