a little trouble burning ISO's
 
I have a question (which may be more about DVD's than about Linux); I would like to burn a copy (i.e. DVD+R) of a commercial DVD that I have. If I run

---------
mkisofs -dvd-video -o /my/homedir/movie.img /mnt/dvd/
----------

I get an iso named movie.img which I would then like to burn to a blank DVD+R. However, sometimes movie.img is larger than the 4.7 Gb (4.3 or so in practice) that a DVD+R can hold.
So then I get...

---------------
$ growisofs -dvd-compat -Z /dev/dvd=/my/homedir/movie.img
Executing 'builtin_dd if=/my/homedir/movie.img of=/dev/dvd obs=32k seek=0'
:-( /dev/dvd: 2295104 blocks are free, 3453633 to be written!
----------------

:-( indeed. My questions are...

(1) Can commercial DVD's store more than 4.7 Gb? How can movie.img be more than 4.7 Gb?
(2) Is there some way I can compress movie.img or otherwise get it onto a DVD+R without losing any data?

Any help would be greatly appreciated.

D.
