Just wanted to add my 2 cents to this issue. After downloading plugin.video.youtube-6.3.0~beta5.zip and after clearing function cache and data cache as you mentioned @anxdpanic , I was able to play the videos that I couldn't play before. I still get the error errno 98 address already in use but this is when I have MPEG-DASH enabled. Upon disabling it, I stop receiving the error.
