@MongoRanger, @DjAnu, etc.:
Thanks all for confirming this problem and the optional work-arounds.
@625alex and I just agreed that not being able to clear out a Video Stream is a high priority issue.
That means fix is targeted for the 5.6.x release (“a few weeks”); or sooner as a hot-fix (5.5.x).
Release timing depends whether or not we run into complications or higher priority issues / bugs. There’s a few things on the radar to be investigated. Lada, lada, lada.
