I got an elite for christmas to replace my busted 20g pro which the hd-dvd addon worked just fine on. Now though, I can't seem to get to work on the new elite that I got. It works on the PC just fine so I know the drive is still functioning. When I plug it in the 360 slows to a crawl, the menus take forever to go away and the whole thing seems really bogged down. Then when I try to update it, it says it can't update it. It shows up in the My Xbox menu but not on the system memory menu so I can't clear the cache or anything for it either. I am clueless now, I have tried just about everything but still no go, even tried on my roommates brand new elite and the same thing happens. Any idea on what I should do? All help would greatly be appreciated. Thank you all for your time.
