Plex Video player (could be related to other video problems also)

Hi I had a post before on the old general forum about videos not playing on Plex webview (its a video streamer for your home network, go to an internal ip address to see all your files across your home network). I didn't have this problem in 4.4.8 and everything worked as intended.

On 4.9 no videos play, I updated the flash on Maxthon and nothing got fixed. I have done some digging and found out Plex uses a HTML5 player which is causing the issue. 

I'm guessing HTML5 is still being worked on for the big 5.0 released but just wanted to post my findings in hope it will get fixed in a later version. 

I am using v4.9.3.1000 just so you know.

Thanks
