Seems that your system has multiple graphics adapters and Intel Graphics has driver installed but is
inactive (is not primary display and/or not has a monitor connected).
Try, if you can, disable others graphics adapters and
attach a monitor to Intel Graphics.
Also you can create a "fake display" using this method:

And use Intel Media SDK System Analyzer tool (included with BDtoAVCHD) to check configuration => BDtoAVCHD Help Menu.
