The projector. To play "Frame Packed" blu-ray you have to use the high-bandwidth Input 8. The Directv receiver is connected to the standard Input 3. It is connected thru my a/v receiver along with all my other sources.
Input 3 will handle all the standard 3D formats - side by side, top and bottom, etc. Input 8 is used for "Frame Packed" because of it being a full 1080P to each eye.
The projector reads the "Frame Packed" signal at 1920 x 2205 @ 24hz. The guys at DP said that the 2205 is normal. Its not the 2160 you would expect to see because there are additional lines of resolution separating the 2 frames.
