Where in the source code of the pages is it held. Also please note I'm not currently setup to alter any aspx or .net based web pages. Unless the pages are based on html5 and javascript.
Look for bootstrap scin from first post, extract, and look stream folder, vlcplayer use video.js but not play mp2t files, hlsplayer no use hls.js, flashplayer look like work with video.js but not play Recordings
That's probably why the recordings aren't playing as there's no mpeg-2 support in video.js. It will play other formats though, are currently asking about mpeg-2 support being added on video.js Slack channel.
Try utilising h.264, webm or flash format for the streaming, by the way the recordings will need to get transcoded to stream (only through web interface with video.js). Sorry!
