btw googling answers such questions in seconds

mirza, I’m well aware of the microsoft universal remote. I’m talking about using my existing universal remote with the 360—for which I need the equivalent vendor code.

And yes, I’ve googled for it, thank you very much.

if you want to invest in a new remote, logitech makes a universal remote that ‘contols everything’ and has specific buttons for the 360 as well. It’s a bit pricey though :-)
