[Dvdrtools-users] DVD-R on A03: Linux max file size problem

[Colin Aspin]

Has anyone any experience with the mkisofs option of splitting the image
size created into maximum 1Gb files to circumvent the maximum Linux file
size (built into the kernel) of a little large than that?  I know I should
modify the kernel to accept up to 5 Gb files but I am not a Linux guru and
don't want to, unless I have to, re-build kernels!  If anyone has the
instructions for such a re-build then I'd appreciate them!

I get the Schilling dvdrecord-pro to write all the files to DVD-R and it
seems to work but I am worried about the inter-file boundary, does the
mkisofs treat that OK e.g. not split files and are the boundaries
unimportant for reading DVD-Rs?

My scripts are below, in case someone finds them useful.

thanks,
colin aspin
