The Colossus does indeed have an IR transmitter. However, it will only work if you have one HD-PVR/Colossus. Since I had more than one, I got the USB-UIRT (which supports two IR leads per USB-UIRT device). If you plan to get a second Colossus eventually, you may want to consider getting the USB-UIRT now, just so you don't have to hassle with the IR setup twice.
