I created a DVD on a windows system. When I mount the DVD on Linux as UDF then the directory permissions are all set to read not execute. In this mode, only root can get into the directories to see the files. When I mount the DVD as iso9660, all the long files names are made into 8 characters. In this mode regular users can execute the directories and read the files, however it is very hard to determine which directory they need because of the short file names. Does anyone know a way to mount the DVD so all users can execute the directories and read the files while having long file names?

Example of UDF mount:
dr--r--r-- 2 4294967295 4294967295 1236 Sep 15 23:51 directory_name

Example of iso9660 mount:
dr-xr-xr-x 1 root root 2048 Sep 15 17:51 direct~1

"Does anyone know a way to mount the DVD so all users can execute the directories and read the files while having long file names?"

I do not think that the problem lies in your mount procedure.

If your kernel has support for Joliet file extensions compiled in then iso9660 will support the long file names. Check to see if your kernel has Joliet support compiled in.

Also you could check a CD. Will iso9660 display long file names on a CD? If it will then Joliet file name support is not your problem. If long file names on a CD will not work then almost certainly you need to do a kernel comile to include Joliet file extension support.
