Re: [Dvdrtools-users] Re: Burning a DVD with > 2GB files -- Linux FS != 32-bit limitations

The problem in my case is with mkisofs ... if I have an iso file that's
bigger than 2GB, dvdrecord can burn it with no problem, but I can't get
mkisofs include files larger than 2GB into an iso. I've googled for
large file patches, etc for mkisofs, but have come up with nothing.

I'm not really a programmer, so I don't have a good idea of just how
much of a pain in the butt it'd be to fix mkisofs, but would love to
have a patch or something that would allow me to include files larger
than 2GB in my isos.

Thanks,

Sean
