After reading a few posts, I've got some major questions about the xbox I hope you gurus can answer. First of all, has anyone had problems with choppy video playback on the xbox with certain game sequences (for me, it was Lord of the Rings, Two Towers...constant choppy FMV)? Now, the other question: what would be an optimal cooling configuration for game system that have limited space? I have all my gaming systems on a bookshelf next to my TV, and it's a bit limited space-wise, so I have to keep them somewhat enclosed, but I at least poked holes in the back of the shelf, so maybe a little air can get out. But is there a better way? Tiny fans perhaps or does heat really only affect them after many hours of gameplay?
