I have no trouble with passthru of composite signals on my HD pro, but nothing seems to pass thru on the component. I am sure I have it connected correctly. I can see the component video through the Slingbox for both component and composite inputs. I have a Tivo HD connected to the composite and FiOS cable box on the component. Is there a setting in the Slingbox to tell it to pass through? I don't ever recall seeing one. Any suggestions?
