I am using the Cinnamon in a 5m length between my Sat and Pre-Pro. I had a Analysis Plus in it's place and the Cinnamon seems to have resolved the "handshake" issues I was having. Picture and sound seem to be good. I would go with the Cinnamon or Vodka on all 3 runs. I think that would keep it consistant. I am also using Trbutaries 9 in a 1 meter from the blue ray to the Pre-Pro. I chose the AQ basically as it was readily available. THe tributaries was on back order in my length.n What Mc are you using?
