For those who had HD trouble with Halo2, an update is now available. It also addresses a couple of live issues. The update is on Xbox live and will apparently give you the option to update. Also, apparently, the nature of the update makes it availabe on live only, and will not be availble on a disc for non-live players. They suggest you take advantage of the two month free service for those who currently do not have live. ** whoops... spelled available wrong.
