Can you please try some of the streams from https://www.youtube.com/channel/UC4R...I7CAwX8_LjQHig to see if decreasing the packet size again allows streaming for longer? The default size is 8192. Also please check in the properties of the file in Mezzmo on the Video tab to make sure the 'Live' checkbox is checked as when I added the streams here it was not detected as a live stream.
