I know this sounds a bit lame - but I don't know. Everything is installed and configured for us in the cinema room. Very unusual for me with tech stuff but TBH over the years I have grown to hate the fiddling about with the tech tweaks and just want to watch more movies with somebody else worrying about that. There are obviously lip-sync settings that have been configured. I will take a look and see what I can find. Pretty sure the MADVR has lipsync.Does the Storm processor not have "auto - lip sync" function?
