I am using a 7842 decoder. I have my input set to HDMI. I get the RAW status that I am receiving AVI infoframes. but when I go to the infoframe map (0x7c) and try to read the 27 bytes of the AVI infoframes, I only get 0s. Actually the whole Infoframe map is just 0s. Why am I not seeing the infoframes packet in this map ? Do I have to do somthing speacial to get the packets in this map.
