the latest working build = #0407 
other newer build have this trouble = since #0415
I think i have found the problem, it's related to expression after the url that cause the bug
Exemple : 
Link not working on LE : https://proxy-035.ix7.dailymotion.com/se...os_stail=1
Link working on LE : https://proxy-035.ix7.dailymotion.com/se...ac_hd.m3u8
The only difference is the expression after the .m3u8 is misinterpreted by kodi [#cell=core&qos_stail=1] , all the links on this plateform/website are generated like that, so to correct that we must force kodi to not took anything after .m3u8
original link of the video : https://www.dailymotion.com/video/x6law2...ist=x5uiot
You can easily reproduce this, i hope my explaination is understable 

Can you post a complete debug log from #0607 (or whatever the latest test build is at the time) which shows you accessing the "not working" url?

Your non-working url is working for me (using JSON):

text:
texturecache.py playw "https://proxy-035.ix7.dailymotion.com/sec(x012cba8530cb5d575ec783f5b1b6ce0)/video/811/775/398577118_mp4_h264_aac_hd.m3u8#cell=core&qos_stail=1"

which might suggest it is an add-on issue or something else specific to your setup.
