The maximum size of a single file on a video DVD is "1 GB - one sector".
This is to allow historical (e.g. Mac OS 9) OS that is not large file aware.

The "largefile awareness" starts with the ability to correctly handle files 
that are > "2 GB - 2 bytes". Mkisofs is "largefile hot" since 10 years 
(Solaris) and supports large files on Linux since Linux started to introduce 
this feature.

As ISO-9660 level 1..2 limits files to 4 GB - 2 kB, we are not talking about
"large file" support but about something different.

If you are using "cdrkit", you use a "fork" that has been created in September 
2006, but that is based on code published in September 2004. As the cdrkit 
project does not do own development, all new features and bug fixes done in the 
official software are missing in the fork.

If you need features implemented during the past 3 years, you cannot use the 
fork, _need_ to use the official software.
