Just edit this file xbpconfig.xml.
Put an * in the remote host tag.
The following will look for an xtream server - <remotehost>192.168.1.100</remotehost>
The following will not look for an xtreams server - <remotehost*>192.168.1.100</remotehost>
Of course this will also prevent you from using an xtream server all together unless you edit the file again to take the * out.
