This is an interesting design in that it is essentially an external box, just bolted to the PJ. The only think I don't like is now the signal is traveling through electronics that it would not need to go through if the card was an actually Port 3 replacement, thus the signal could be potentially cleaner than actually going through the port 3 card.
The other interesting thing would be to be able to hook it up to port 5 because port 5 on later model Barcos like the Cine series have better electronics than port 3 which retains the older design. So, whereas port 3 is better on older Barcos, port 5 is better on newer Barcos.
However, I must say, this is excellent work and quite a fair price. Do you have any intention of attempting to do an HDMI version that would support 10 and 12 bit?
