[mythtv-users] Mytharchive failing to create iso

I am experimenting at archiving shows to DVD and having some trouble
creating iso images with mytharchive.  After failing on 3 separate
attempts I checked logs and the error is "mkisofs: File too large.
cannot fwrite 32768*1" and that was after writing a 2GB mythburn.iso
file.  Anyone know what is causing this and how I might fix it?

I did some googling and don't know why mkisofs is failing.  I then
tried using k3b to create the iso and it works.   This machine is
running kubuntu edgy with the standard .20 myth frontend packages.  It
would help to know what specific command mkisofs is running with
mytharchive since it fails that way and works ok with k3b.
