Hello all, I have a 3D TV and was trying to watch some 3D videos (side by side) on YouTube. These videos on YouTube have a specific '3D' designation, including a little 3D toolbar in the bottom right corner. However, any time I try and view these in side-by-side mode, I hear sound but see no video (it's just a blank black screen). Anybody know what the deal is? Other YouTube videos work fine.
