The GoogleTV is not capable of capture in the sense you're thinking of.  
It has a dedicated hardware path that decodes the video, does whatever 
transforms are requested, composites the GoogleTV UI on top, and outputs 
it.  At no point is the decoded video ever made available to the Linux 
system such that it could be stored to disk.  It may as well be your 
monitor/TV overlaying the interface.

There _are_ HDMI capture cards.  BlackMagic makes a PCIe x1 card that 
runs around $80.  However you will not find one that will touch anything 
with HDCP.
