If your game freezes at the starting menu AND you've downloaded DLC then read this.

I've witnessed this problem more than once before, although I am unsure of what the cause is I can only guess it is because of the constant turning off of plugs to my xbox, just like how if you are offline and set your xbox's time it will be reset to 2005
if you turn off the xbox by the plug.

So anyway to get to the point, if you begin the game and then it says 'Loading downloaded content' but then freezes (you will know when it freezes because you cannot hear the music in the background, also pressing the 'home' button on your xbox won't show
up). Then all you have to do is simply go back to your install disc and re-install the DLC...what it has done is completely erased your DLC despite having it saved in your storage section on your xbox.

The install loading screen will pop up and seem to take a while, there are times when it won't freeze but it will take a very long time (the average wait time is 5 mins) if it takes up to 10 mins or more then I suggest you turn off your xbox and then retry,
I did have this problem and then after my 3rd retry it loaded pretty darn fast.

Re-install the DLC and viola! it should now work.

Skyrim issues

Yes, I know you've cleared the cache, etc. I would like to ask you to do it again, but first delete Skyrim, and all of it's content EXCEPT saves (you wanna keep those). Then redownload Skyrim and any DLC you deleted (if you had DLC) and clear the cache again.
Check if it runs better. Also, I suggest adjusting when your game autosaves. This will be in the options/settings section of the pause menu; autosaves will almost always cause your game to "freeze" - when in reality it's just a bit of lag from the autosave
starting.

 

Spartan Ops videos not playing

I've installed the game to my consoles HDD and have had the game since launch. When I start Halo 4 and go to Spartan Ops, and select a video to play, it plays fine. However when I select another episode to watch, the screen flickers for a bit then kind of
freezes (my console doesn't freeze though). I have to press the guide menu and switch in between the menus. This is probably a game glitch. Sometimes, going to the Halo 4 start menu then going back to spartan ops and selecting an episode to watch works. Other
times the episode won't play. Maybe they might correct this via an Xbox Live Update. Best to use the Youtube App on your console (if you've downloaded it) because of this.
