Baud rate problems using serial communication with xbee and micro controllers

I've hooked up a playstation 2 controller to communicate serially between two micro controllers using the TX and RX pins. After going wireless with xbee the Baud rate seems to be set at the wrong setting. Every thing works when I take out the xbee and have it communicate directly through the pins. or just have it sent directly to the xbee using a terminal program. Just when i have it sent through the micro controller the serial seems to be all jumbled (yyyyyy or something similar). Any ideas as to why?

Any ideas as to why?

No code. No illustration of how the Arduino, XBee, and play station controller are connected. No mention of the type of XBees in use. No mention as to how they are configured. So, no.

It required that the arduino that was connected to the ps2 controller be reset.
