I just looked at the growisofs man page, and it looks to me like theoretically 
one can go from a bunch of files to a dvd directly, and on a glance it 
appears to require no intermediate files.

Personally, I had horrible problems using growisofs and went back to using 
mkisofs/cdrecord for DVDs, but others might have more success with growisofs, 
and it's possible that 2008's growisofs is better than 2005's, which is about 
the last time I tried growisofs.

I'd be interested to hear if Ingo can use growisofs, in conjunction with a 
script, to write to the DVD without intermediate files.

By the way, Ingo and everyone else -- I've created a couple Ruby programs 
to "best fit" sets of large files onto DVD sized intermediate files, and 
assuming one can get growisofs to work right, they could be used to "best 
fit" sets of large files directly onto DVDs. My "best fit" algorithms are 
better than "put the next biggest one that fits", because "put the next 
biggest one that fits" is usually but not always optimal, so I use a 
backtrack algorithm instead.

If anyone wants a copy of the Ruby programs, I'll put a free software license 
on them and send them to you.
