Comment (by jpilk):

 Peter.  Thanks again.  Simple playback of DVB radio is now fine, but
 navigation and editing are not.

 Jump Fwd, Jump Back, and Skip Fwd seem ok.  Skip Back, and quitting at the
 start of 'Cut to End' are broken.   Going to that point in the Editor,
 moving back 2 x 20 s and restarting plays for about 3 s.
 Here's -v playback,timestamp for that:
