FS Multiplayer, Wideview, & SB3

Does anyone know how to improve MS multiplayer in FS2004 so that when used with wideview as a second and third view, and connected to VATSIM via SB3, the multi-player A/C (i.e. the other pilots on Vatsim) movements are more smooth on the client views? I am currently using WidevieW to provide me with two extra views, front left and right. The centre view is the server and the side views are the clients. I connect the server to Vatsim via SB3 and then the clients via FS multiplayer to the server. I can see other A/C correctly, its just that the movement on the clients is not smooth as compaired to the server which is connected directly to Vatsim. I am thinking that the problem is with MS multiplayer. Has anyon e else had this problem, and if so, how do you resolve it?

Thanks.
