There is no DRM restriction.
Where did anyone get the DRM idea from?
There is definately DRM built in here, as I have seen it. But i have a feeling it is for movie playback (to stop piracy).
I ran into this issue trying to play a blu-ray from my PC to my TV via a HDMI splitter box.
As for 3d DRM, I am not sure, you may want to ask on the NV forums. I know for a fact that there is an approved list of devices... if other devices work I am not sure.
