The card they had running was carrying both audio and video.
I believe when this card comes out, its main purpose is video only. In order to do audio and video, you will either daisy chain or run two outputs. (when I asked, they said you could do both.) I don't believe they are sure which way they are going to go yet.
If it is daisy chained, the 861 would then have a card that has an input and output. It would be a bit more money because it would need both the Silicon Image receiver and transmitter.
Over at the Silicon Image booth, they had it plugged into a Panasonic with HDMI. They cable run was 25 meters.
