Despite jwhite's kernel fix, http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=... I find I have to use 'norock' on some discs, e.g. Macromedia Studio 8, http://bugs.winehq.org/show_bug.cgi?id=9467 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: $ ls /media/cdrom/ -l total 3668 dr-xr-xr-x 2 4294967295 4294967295 40 2007-07-24 15:54 AUDIO_TS -r-xr-xr-x 1 4294967295 4294967295 2144972 2007-07-17 20:18 DKNYDeliciousNight -r-xr-xr-x 1 4294967295 4294967295 1602372 2007-07-17 20:18 DKNYDeliciousNight.exe -r-xr-xr-x 1 4294967295 4294967295 1616 2007-02-14 06:34 Readme.txt dr--r--r-- 3 4294967295 4294967295 560 2007-07-24 15:54 VIDEO_TS

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? - Dan
