Comment 39 for bug 10550

It looks like this bug was reported in Fedora too, but there is no resolution there either:

As Martin said earlier in the bug, this probably needs an extra option implemented by the filesystem driver to ignore disc permissions (as they might have useful details for non-movie discs, you don't want to ignore them outright).
