If you grabbed a copy of Knocked Up on HD-DVD and are having troubles with the Xbox 360 HD-DVD player and getting this disc to even load, you’re not the only one. I spent a good hour tonight trying to get this disc to play, including a return trip to Best Buy because I thought I got a crap disc. I finally found a solution over at AVS Forum. The people over there are amazing.

1. Go to the System blade
2. Go down and select Memory
3. Go down and Select HD Player (NOT Hard Drive)
4. Go down to the bottom entry. More than likely, it will be the largest entry in the list. When the cookie is fully downloaded, it will be 11 MB in size. When I checked for the cookie, it was 1MB in size (at the time i stopped the download). [for me, it was the first in the list, but I deleted all entries in the HD-DVD drive]
5. When you have found the entry, DELETE IT.
6. Retry starting the movie and wait for the loading screen. When you see it, you will know you have succeeded.

Once you do that, the disc should load up fine and come to a loading screen where it will sit for about 10 minutes. Do NOT hit Cancel, because that will just mess up the cookie download, which will bring you back to the same point of the disc not playing.

Seriously, if either of the HD disc formats wants to win the format war, they need to stop making things so damn complicated for the average user.
