Despite jwhite's kernel fix,
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9769f4eb3fad2dd53a5d24c81ee5f7f05450742b
I find I have to use 'norock' on some discs, e.g.
Macromedia Studio 8,

Microsoft Dynamics GP demo,
http://bugs.winehq.org/show_bug.cgi?id=8178
... and the stupid DKNY perfume promo DVD-ROM that
came in the newspaper today.
Running it with Wine yields... a black screen, as the flash player can't
get at its data.
Mounting the DKNY disc with -o unhide or -o norock lets it work fine with wine.
Here's what one sees without either flag:

(The VIDEO_TS directory is not searchable, but the app works anyway. )
norock is similar, but VIDEO_TS is searchable.
Given that these poorly mastered discs are turning up periodically --
widely distributed -- it seems like it might be time for another kernel change,
or at least some userland kludge that does a remount.
The heuristic I imagine is:
If the top level directory has any subdirectories that are
completely nonsearchable or nonreadable, remount with unhide.
What say? Would this help users more than it would hurt?
