AD9888 HDMI compatibiltiy issures with modern pro camcorders

I am looking for an expert on the AD9888 HDMI Input Chip. So I am hoping somebody can give me an idea on a problem we have with the AD9888. 4 years ago we designed a few of this chip into our "presentation recorder" which is a special kind of lecture recorder. This is not a new design but we want to extend the life of this product. 

 

Until recently, with most consumer cameras this worked fine. Now we are seeing some camcorders which do not connect with our AD9888 HDMI Input. Mostly this problem occurs with the professional camcorders and cameras.

 

 

- Is it possible, that these (HDMI 1.4) camcorders are not backward compatible with the HDMI 1.1 AD9888?

- Do you know of any issues in this area and tricks to overcome this?

- Do you have a proven setup or script for the AD9888 which will definetely work with a HDMI 1.4 camcorder.

 

The latest case of failure was with a Canon XA10 professional camcorder.

 

 

Perhaps you are able to refer me to a person or a forum potentially helpful with this question?

 

 

Many thanks and best regards
