You originally said mkisofs finished quickly. It shouldn't run any  
faster than your disk drive(s) can copy the data. My single PATA  
drive can only sustain 15 MB/sec in that combined read/write  
situation but can single-task read 50 MB/sec if its copying to  
gigabit ethernet or my gvinum striped SATA drives.

I believe your problem is with Nero, not with mkisofs. Something  
about Nero either does not like a non-video DVD or something is wrong  
with your file transfer from FreeBSD to Windows. Many ftp clients  
(not /usr/bin/ftp nor /usr/libexec/ftpd) have problems with 2G+ files.

I grabbed ~4.6G of files and used your exact command line structure  
but outside of a script. All files were on a gvinum striped pair of  
SATA drives, so it sustained about 50 MB/sec combined read/write.

Then from MacOS X 10.4 (Tiger) pulled the file via command line ftp:

ftp> mget junk.iso
local: junk.iso remote: junk.iso

(notice Apple still has a problem counting on 64 fingers, "348297216  
bytes received", but it really did 4643264512 as it says above.)

And Apple's Disk Utility was perfectly happy to mount it. Stopped  
short of burning it but files extracted from the iso matched md5 with  
their originals.
