What browser do you use? What exactly does "won't work" mean?
I am also having the same troubles, i am using google chrome on windows 8 and also windows 7. It takes over an hour to even load a 20 minute video, that's with pausing it its been a few weeks now, it's really frustrating. I have tried everything, even re-installing google chrome, plug-ins. It plays youtube fine, just not any other tv streaming sites. Anyone help me figure this out, I'm ready to throw it out
