Can we not use gizmo as a remote to tell another client to play a movie and that movie have the original audio???
Yes, you can. From the sounds of it, you are actually using Gizmo to treat your MC Client as a DLNA Renderer, rather than an "MC Client." First, make sure the Client is set up correctly:

Now, this is probably where you are having the issue: even though you are loading your "Main Library" onto your Client PC, you still need to load your Client PC as the "Choose A Server To Play From" in Gizmo for it to act as a MC Client remote control. In other words, you should have two Access Keys (or IP addresses) entered into Gizmo; one for your Server and one for your Client. When you want to control your Client, go into Gizmo Settings -> Mode and switch to your "Client PC Server." If you just use your "Main Server Server" to play from, it treats your Client as a DMR (thus the transcode).
I know the terminology can be a little confusing; it's tripped me up before too.
