DVD:filenames more than 103 characters long?

Is there a way to burn a dvd (or a cd) adding files with filenames more than 103 characters long? It seems impossible using k3b because the limit of 103 characters is fixed by joliet standard. So k3b adds files to compilation but when I try to launch the burn process it stops saying that is going to truncate files with filenames too long...
Thanks in advance for any comment of suggestion you can give me!

On a DVD, I think you could remove Joliet support, providing that UDF was enabled. If UDF is used to read the disc then, longer filenames should be no problem.

Thank you for the answer. I've found out that joliet is needed only by Window$ and it's limited to 64 characters per filename. Then there's joliet-long format which supports up to 128 characters filenames. But if I want a linux-only dvd, I can use rockridge extension, which seems to have no limitations on filenames' length, but dvd remains unreadable on Window$ machines.

well, take this without guarantees. i've tried to make an ISO image with mkisofs that contains a file name longer than 103 chars. the file is contained in the single directory i want to copy.

here the commandline: mkisofs -r -J -l -D -L -joliet-long -V -P -p -abstract -biblio -o ./myimage.iso -graft-points /=/mnt/hdb/musica/italiani

this is the commandline output generated by x-cdroast. some options may be superfluous.
then I tried to mount it to check out, with:

# mount -o loop myimage.iso ./somedirectroy -tiso9660

effectively mkisofs created an ISO image containing one file with a filename exceeding 170 chars. maybe it works for you too. try to make an ISO image using mkisofs and then burn it.

hope this helps
