Just got the T-Box installed today and are having issues with HDMI. My setup is a Sony KDL-40EX400 with Sony DAV-DZ610 home theatre system. Problem is when the T-Box is plugged in (via HDMI, the home theatre is plugged into HDMI1) it causes the home theatre system to switch to the TV input when trying to watch TV or USB. This occurs even if the T-Box is turned off.
Is this a known issue and can I get it to all work together nicely via HDMI.
