I am having an issue with backing up my DVD's. I have taken the DVD, extracted the movie-only, removed encryption, fixed the IDF's to where I can view the DVD on my hard drive so I know that the DVD files are good. I can read them from Windows and Linux. The problem that I seem to be having is when I burn them to DVD. I use growisofs from the command line like this (I am not at my computer right now so I am not totally sure that this is the exact command line) :
growisofs -dvd-video -Z /dev/sr0 /my/dvdfiles/
I have also used mkisofs like this (again I am not completely sure of the command line but this is what I remember) :
mkisofs -dvd-compat -o ~/dvd.img /my/dvdfiles
and then I use growisofs again because of the DVD+R's
growisofs -dvd-video -Z /dev/sr0=/my/dvdfiles
I have also used K3b to do all of this work behind the scenes and all in all, I get the same results, I cannot read the DVD after the burn is complete. The thing I have noticed is that I can mount the DVD somtimes from the same drive that I burned it with but nothing else.
I have been searching but I cannot find the info I need. I also want to be familiar with the file systems for DVD's. I can use the -R RockRidge and -J for Joliet and in K3b I can use udf. What do all of these formats mean? Do they have to do with the readability of the discs? Thank you in advance.
