A lot of people have suddenly found that their XGD3 games and AP2.5 protected XGD2 games suddenly don't boot, even though the dashboard hasn't been updated. Their consoles have also been flagged for bans. Check this thread here: - http://www.ixtreme.net/open-forum/18685-disc-not-supported.html There's another thread that's just been started on Xbox-Scene which will no doubt grow larger as people report the same problem. My guess is that MS are now updating the DAE table silently over Live. Anyway, you have been warned! I would advise staying off Xbox Live until we know what's going on.
