Okay, here's how I interpret what you sent. I really don't have any
idea how they are smoothing so I gave you 2 options one a WMA and the
other wilders. Looking at this though I really have my doubts that
this is the DMX. Smoothing after the fact is not going to remove lag
and the DMX is supposed to be about low lag. See what you think
though.
