So I picked up a Xbox 360 slim 4GB + Kinect bundle and was wondering if anyone has any first hand experience with DLCs and the internal flash and/or a USB flash drive?

I've found conflicting posts on various forums after googling around for answers.

(In particular Fallout 3 GOTY edition, which has all the DLCs. On various forum posts i've seen people haven't been able to install DLCs on the internal flash or a USB flash drive but there was supposed to be an update that fixes this?)

Looking for someone who's done this first hand. :) Otherwise i'll have to fork out the cash and hope for the best, since I don't think you can return games for cash, only store credit..
