Comment 20 for bug 16722

That is a super bad idea. Read errors can happen for various reasons, including obviously defective disks, purposefully standard-violating disks (unfortunately a lame but common practice to attempt to contain DVD piracy). Advising the user to set region upon read error would a time bomb. It will cause many many users to destroy their drives accidentally.

Besides, your drive is supposed to be zoned when you buy it. I fail to see how the media player is to be blamed.
