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

[Colin Aspin]

Simon,

Thanks, yes, we are using 2.4 kernel:

address@hidden ~]$ uname -a
Linux maia.hi.gemini.edu 2.4.2-2 #1 Tue Aug 28 13:41:29 MDT 2001 i686 unknown

and yes, we did find this out also, and re-did the script with bash and it
helped but not to the extent of allowing 4.7Gb files.

cheers,
colin
