Same here, my licensed VDH will stop on this particular HLS video everytime at 27% download; but it does not crash, it just stops. If other downloads are running in parallel, they also stop completely. The downloaded video is available after conversion but is limited in duration to the stop spot.
Problem : I have access to this paid video for a limited time, that is my access will stop in 7 hours. So I guess no solution will come up before ;-(
Other issue for all downloaded HLS videos under OSX10.14, the converted mp4 format is not compatble with Quicktime but runs ok with VLC. Strange !
Thank you anyway…
