Playing 3D Blu-Ray using a PC, Mitsubishi WD-82740 & NVIDIA GeForce GT 430 video card

Please HELP. I want to use my (Win 7/64-bit/Intel i3) PC to play commercial Blu-Ray 3D DVD disk movies (like Lion King). My PC (which has a Blu-Ray player) is directly connected to my TV (Mitsubishi WD-82740 DLP 3D TV) via a HDMI cable. I have both TMT 5 and PowerDVD 11 programs.

I also have a 3D Blu-ray player which is connected to another port on TV and I have no issue playing Lion King in 3D. I want to return it and just use the PC to play 3D Blu-Ray. The Lion King works fine from the PC but it is only in 2D. The TMT5/PowerDVD have options for automatic/side-by-side/up-down for 3D contents but I don’t see option for frame packing which I heard commercial 3D Blu-Ray use. My TV is a 3D TV (in addition to checkerboard, it can do side-by-side, up-down, and it is compatible with HDMI 1.4). I also ran the TMT utility that checks my hardware/software/TV capabilities for playing 3D and it tells me my system meets all the requirements. PLEASE HELP… WHAT am I missing and NEED to do to play 3D?
