It seems that Internet download manager does not start downloading streaming vdieo through JWplayer (which are in fact small .ts files).
I thought it is becaue IDM can not detect .ts files so tried converting a sample mp4 into .ts files and created a m3u8 and tried playing the video using video.js but IDM starts downloading a big ts file which contains all parts.
Is there a special technical protection in JWplayer or there is copyright or something else? Are my videos being protected from downloading if I buy a premium Jwplayer account?
