Slow menu response on MP client with TV-server connection (1 Viewer)

[_Spiff_]

Hi!
I have a MediaPortal installation with both server and client on one PC which works great!

Now am I trying to add a second client on another PC.
The problem is, after adding the TV-server/client (for connecting to existing server) I get slow respons when navigateing in menus especially in the TV-menu on the client.
If i unplug the network cable I get an error message that the connection to the TV-server was lost and then the menus works normal again. I have tried to shut down the firewalls on both computers but it did not made any difference.

Help and suggestions are much appreciated!

I am currently using MP ver 1.0.2.
The server/client system is: AMD Athlon 64 X2 4400+ 2GB and Win XP Professional.
The client system is: P4 3.2GHz, 1GB and Win MCE 2005.

Anyone?

To add more information to my question I have also noticed on my router that it is constantly communicating with the server even if I am in the home menu.
I also forgot to add before that I am using MySQL ver 5.0.67 and MP Web Interface plugin.

Am I the only one having problem with slow menu response on multi seat setup?
I would very much appreciate help with this because I am stuck!

Thanks in advance to anyone that can help me with this!
