It as nothing to do with size. You are trying to burn a CDR format onto a
DVD. They are not the same. You need mkisofs and cdrecord versions that
have DVD support, i.e. dvdtools and dvdrecord.

Does not the latest cdrtools include support for DVD burning?
At least that is what I thought, as it is mentioned in the
cdrecord man page.

I have already burnt some DVD with cdrecord that work
without flaws. Both video and data DVDS.

If I split the backup.tar.gz file mentioned above in
pieces lesser than 1GB in size (giving 3 files), I have
success in reading the resulting DVD. That is what
is making me believe that the file size is what makes
trouble in this case.

Nonetheless I will test with dvdtools.

2GB. It's the same for UDF, so you can't get around it that way either
(that's why DVD .VOB files are split into 1GB chunks).
