guys,

do you know where can I download update file for the xbox 360 so that it can play .mov hd files..I don't have xbox live connection so I have to burn it to a cd before updating my console..how do I check my system version in xbox 360?..how do I know if the fall 2007 update is installed on the console?..I bought my xbox in may 08..when I try to play the .mov file,it states that an update is needed to play the file..any ideas guys?
