used your suggestion to add a second cheap video card to use for audio via HDMI since my receiver can't passthrough 3D. Still working out some glitches: e.g. if not in AutoPlay, playing 3D from TMT5 sends a garbled signal. If in AutoPlay, sometimes starts playing in TMT 5, but most of the time, it displays the picture but with a weird "bouncing" at top and bottom of display. Stopping the Blu-Ray and starting again usually works.
In any case, my question is how do you force WMC to open on the primary display (projector)? WMC always starts on the secondary display (receiver), and I have to disable it, then re-enable it to keep it on the primary monitor. I have tried to close and open WMC a few times on the primary display but it always starts on the secondary. This is a problem because since there is no display hooked up to the receiver, I can't "see" anything to drag and drop WMC on the right screen.
Thanks for your assistance and getting 3D partially working on my HTPC (far better than not having it at all).
