The difference is not in the QDEO, but in the MediaTek decoder. The BDP-103 uses the MediaTek decoder for all de-interlacing, scaling, and frame conversion. The QDEO is only used for Contrast Enhancement, Noise Reduction, and 4K scaling (exclusive to the BDP-10x series)
On the BDP-93 all de-interlacing, scaling, and frame conversion were done through the QDEO, as well as the same video enhancement algorithms.
