Since late 2020 I have been getting occasional 20-second hangups on 
moving from playback to the cutlist editor, mostly but not exclusively 
during DVB radio playback. Issue #344.  I don't think anyone else has 
reproduced this, the logs didn't help, and I developed editing 
strategies that seemed to make it less likely.

Usually I have had 'Interactive TV' disabled.  I don't remember why, but 
I had the impression that doing so reduced the likelihood of some other 

During this trial I have re-enabled it, and the mysterious hangups seem 
to have gone away, in both fixes/32 and devel/ffmpeg-resync.  The 
display gives hints about cutpoint location too. :-)
