I couldn't find my original thread on this subject, so I thought I would put it here and you can move it to the corresponding thread later...Gefen did send me an upgrade chip which was supposed to make their HDMI switchers play DD+...but it didn't work...I will be back on the phone with them Monday and hopefully their tech team will be able to figure this out...(It appears I am the DD+ guinnea pig for HDMI switchers?)... 
As of this date, none of the Gefen HDMI switchers are passing the DD+ signal correctly. It is frustrating, but I'm sure it will be worked out shortly.
