Writing files several times takes more space on disk than writing them
all at once. Perhaps

There's a >10 year old kernel bug which could be causing this.
What is the size of the filesystem in bytes? Use df with the DVD or
loop-mounted iso file. Then run isoinfo -d -i /dev/hdd and multiply the
sectors number by 2048 - is this more than the size of your
/tmp/dvd.iso? If so, you found the problem and confirmed the >10y kernel
bug.
The solution to this old kernel bug is to add -pad padsize=10x75s to
your mkisofs or growisofs command line. Also, you won't see this bug on
a DVD+RW which has been written once before with more blocks than you're
currently trying to read. If this padding doesn't fix your problem, post
again.
