Play DivX from USB source
You can use a portable USB memory device to play content on the Xbox 360 console. On this page we will take a quick look at formatting (optional) a USB key and playing content from it on the Xbox 360 console.
Optional -- How to format USB stick

Connect the USB to your computer and wait until it is ready (if it is the first time using it, you may get the new hardware prompt, but under XP or newer, it should not need any user interaction).
When ready, go to My Computer (icon will either be on Desktop or Start Menu) and find your USB source (usually says Removable Storage). Ensure that it is the correct source and that there is nothing on it that you need to save. Right click it and click Format. The machine will automatically set the capacity settings correctly, although it is always a good idea for you to take a look here and see just how much capacity you have for multimedia content (mine says 960MB).
Make sure File System is set to FAT32, Allocation unit size is Default allocation size and that Quick Format is selected if available. The Volume Label can be changed to whatever you want it, and it will represent the name your hardware will read from your USB key. When you are ready, click Start.
