A day or two ago when i started my computer up it needed to repair something since then i have been unable to stream any videos through firefox apart from youtube. It either says "no compatible source was found for this media" or " this video fine cannot be played. (error Code: 214000)". I have tried removing and re installing fire fox, I have my direct X up to date, i have adobe installed/ up to date. I downoo9aded the Microsoft media feature pack, I have tried disabling all my addons/ extensions nothing seems to work. If anyone could help me out that would be amazing. I really dont like google chromes set up but if that is the only way i can stream videos i might have to get used to it.
