I've got a 360 Elite, bought a couple months before the black ones came out. There are 5 profiles on it, and the drive is about 2/3 full, with maybe a couple dozen games installed on it. It seems to work fine for most things, but there's one thing that's completely outrageous. When I hit QuickPlay from the home menu, it takes over 45 seconds to generate the list. If I'm playing a game that was chosen via that list, and I exit to dashboard, I have a blank screen for another 45 seconds as it comes back to that list again.
Has anyone else seen this? Is there a fix for it? I'm pretty sure when QuickPlay first came around, it was only about 10 seconds or so to come up.
