Some more detail.

The system I'm trying to connect to the xbox 360 is called a Bubble by 'Bright things'. This is an interactive DVD game for kids which uses a remote console to guide the DVD game using the IR sensor of the DVD system (in this case a Xbox 360).

To set up the Bubble you have to enter the code of the DVD system you are using so the console can transmit to the DVD player. The Bubble comes with a list of DVD makers and 4-digit codes, but for Microsoft only has the original Xbox listed (code 0522) which doesn't work. I was hoping someone out there knows the 4-digit code that will allow the Bubble console to mimic a Xbox 360 remote.

Hope that helps (and fingers crossed someones knows!)
