I don't approve piracy, but I do approve the right to make backups of your legally owned games. Now, trying to figure this out, I'll put this question here:
The people who can't boot theirs backups, are they changing the booktype to
DVD-ROM before burning theirs discs, or are they using the one by default (DVD+R)?
If this is true and the new dashboard has a new check protection, maybe it's checking from what kind of disc the game is trying to boot...

Nice try, but LT firmware reports DVD-ROM whether it's true or not.
Once all the facts come out on this, I think some people will feel pretty silly for hitting the panic switch.
