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. |
