I posted about this yesterday and I've read a lot of comments in various places. Based on what I've read: -
1. The game works fine with pre-beta dashboards.
2. Not all users of the beta dashboard are affected.
3. All beta dashboards after and including 2.0.12581.0, with or without avatars, may be affected. Earlier beta dashboards may be affected too, but I haven't read any comments about them.
4. Some users have said it works fine with beta dashboard X, but upgrading to beta dashboard Y lead to the "This disc is unreadable" error, even though other users claim to have no problem with either dashboard X or Y.
5. Fable 3 is the only game affected for now. The game is recognised by the console and will even install to the hard drive without issue. The error only appears when the game is booted.
What's certain is that the issue is real and not just people spreading lies or not knowing how to burn a disc, but there seems to be no logic to it, as it'll work for one person, but another person with the same drive, same firmware and same dashboard version will get the "This disc is unreadable" error.
