Oppo 103 digital processing


Can someone explain the two HDMI input features on the new oppo 103? From reviews and comments it sounds as though ANY sound source, such as a cable HD broadcast could be processed by oppo features for a better experience........or am I way off base.

Sorry for the uninitiated question -

Would there be a significant enhancement to my video quality if I hooked the HDMI output from my Motorola/Comcast HD cable box to the HDMI input on the Oppo 103, then ran the 103's output to my display - passing my Cable viewing through the 103?
If the Oppo would does decoding and HDMI input switching, it would be intersting if someone build a Multi channel HDMI DAC with volume control. You could run your HD receiver, possibly a gaming device into the Oppo, and the Oppo into the DAC. No need for a SSP anymore.
