Why would a valid DVD show zero files on Linux?

Here is the table of contents mounted three ways. First udf, then iso9660, then iso9660 nojoliet. Only the udf version works with the application. Note that the huge udf filesizes are not a mistake - this DVD is also offered as 7 CD set.

[iso9660 nojoliet:]

Could it be that you are using some old kernel, say, older than 2.4.13, that enables the "cruft" option when it sees a big file? (You should see the corresponding messages in the logs.)
