UPDATE:
It seems that it's just one file that seems to be gumming up the works on my Videostream. I try opening up any other file (in that list from the screenshot I posted above) and they stream just fine. However, no matter if I try opening the one file very first or after I've tried opening another, it freezes the software apparently. Glad I could get this figured out! Sushi, hopefully you can figure out your issue too... but looks like it might be the software freezing for one reason or another.
One thing to add: just closing the videostream tab and opening a new one won't fix the freeze problem. You have to shut down the chrome browser completely. Otherwise all your files will come up "Video Title" and never load, even if it was working before you tried opening the corrupt file.
