You (propably) could get your winchester dvd-flashed.

Well, bad update explot is here, and InvoxiPlayGames made FreeMyXe, and it gives u the cpu key. Do you know what that means?

By dumping the nand and using that fpu key you can discover what dvd key you have.

Then you just buy a dg-16d4s, flash it with a firmware with that key and you can play backups!

Well, that is just my theory, i didn't try it yet, cause i don't have Tony Hawk's American Wasteland.

UPDATE: Oh boy, I have it

Now a question for those that are more into dvd flashing: how can i trick my xbox into thinking my dg-16d4s is a dg-16d5s? (I heard somewhere that you can do that)

Update: Nevermind that question; i found out myself. Now i'll only need to get a dvd flasher.

UPDATE:

Question: Can i flash a firmware made for dg-16d5s to a dg-16d4s drive?

The newest update: Someone did that now: https://www.youtube.com/watch?v=CwNUK-IsT2k
