I have a 360 made 6 weeks ago and Live wants to take up 128 megs of its space with an update. WIthout the update I cannot connect. Is it telling a porky pie, or is it really going to blow away half of my available space (i have no memory card nor intent to buy one yet)? Also, two bonus questions: 1) Can I use a USB card or other in lieu of an official xbox mem card (I doubt it) 2) DivX playback--is this supported via the "official" 360 updates? I put in a disc with a divx file on it and was told I needed an update (which of course I cannot get without a live connection...). Thanks!
