I got both problems, but my Xbox hasn't broken down since. He meant that, from Xbox to Xbox 360, the White/Black buttons were changed to a completely different place. I tried playing a Xbox game that needed them, but it appears only one of them even exists on the 360 controller setup, so it failed to work fully.
But you're just used to PlayStation controls, Nat.
I thought he meant something like "They took the Playstation controller layout, but why did they go and remove L1 and R1 and instead put a white and black button on the right side?"
The only Xbox game I played on the Xbox 360 was GTA:SA. When I read reviews for it, they claimed that helicopter controls were annoying because Black and White were used for rotating left and right. Since I played it on the 360, I didn't have this problem because the left and right bumpers allowed me to rotate left and right. Still took me forever to pass that attack helicopter flight school mission, though.
