with version 6.1.4 there are very short stops in videos (error reported and accepted).
In version 6.1.5 the show (the same one!) just hangs in the middle of the show between two videos!
With version to version the SW becomes more buggy.
two reinstallations (first a revert to 614 and 60x) now resulted in correct playback.
However, the previously reported stops are still present.
