I was running HD (D-Theater tapes) on my Barco 812 before going digital a few years back. The 808 is very similar... the key to that experience working well was using a Lumagen processor to deliver 48Hz to the projector. This allowed the full resolution HD bandwidth to fall under the projector's maximum and avoid ringing issues. 1080p60 looked softer and had some ringing. Having said that it still looked significantly better than DVD...
