No, the box is connected to the TV directly. But it might the same issue as with the AV Receiver?

Did you use the same HDMI input on the TV that you use with your BluRay player?
I guess you already tried all possible 3D settings on the TV.. you could invest in this rather expensive gadget:

I use it on my HTPC with an AMD graphics card and it works great, but no guarantee that it works in combination with the Vidon Box. It should however work.
