Hi Charles,
Just a quick response. I have more or less the same set up as you mentioned, I have the 50inch VT30 (I wanted the new AE5000 projector too, but the price was way more than the outgoing model!).
Anyway, I just wanted to say it does all work, but the BD player has a bunch of settings that need to be looked at closely. The 875 is old school so has no issues with audio in from the BD via HDMI and out again. The 2nd HDMI goes straight to the TV/projector. But its the audio and video settings that I found odd and needed some extra time to tweek.
Sorry I can't be of more help right now, it'd take me ages to figure out what I eventauall did, but I recall the BD player was the main issue. Esp the 3D setup.
Best of luck, TnA
PS. Would love to know how the projector is performing in your setup once all is up and running.
